This package will carefully use 'unsafe' for performance reasons in specific places.
You can build without unsafe use by passing the safe or appengine tag
i.e. 'go install -tags=safe ...'. Note that unsafe is only supported for the last 3
go sdk versions e.g. current go release is go 1.9, so we support unsafe use only from
go 1.7+ . This is because supporting unsafe requires knowledge of implementation details.
This package understands the 'unsafe' tag, to allow using unsafe semantics:
- When decoding into a struct, you need to read the field name as a string
so you can find the struct field it is mapped to.
Using `unsafe` will bypass the allocation and copying overhead of []byte->string conversion.
To install using unsafe, pass the 'unsafe' tag:

Custom Encoding and Decoding
This package maintains symmetry in the encoding and decoding halfs.
We determine how to encode or decode by walking this decision tree
- is type a codec.Selfer?
- is there an extension registered for the type?
- is format binary, and is type a encoding.BinaryMarshaler and BinaryUnmarshaler?
- is format specifically json, and is type a encoding/json.Marshaler and Unmarshaler?
- is format text-based, and type an encoding.TextMarshaler?
- else we use a pair of functions based on the "kind" of the type e.g. map, slice, int64, etc
This symmetry is important to reduce chances of issues happening because the
encoding and decoding sides are out of sync e.g. decoded via very specific
encoding.TextUnmarshaler but encoded via kind-specific generalized mode.
Consequently, if a type only defines one-half of the symmetry
(e.g. it implements UnmarshalJSON() but not MarshalJSON() ),
then that type doesn't satisfy the check and we will continue walking down the
decision tree.

Running Benchmarks
Please see http://github.com/ugorji/go-codec-bench .
Caveats
Struct fields matching the following are ignored during encoding and decoding
- struct tag value set to -
- func, complex numbers, unsafe pointers
- unexported and not embedded
- unexported and embedded and not struct kind
- unexported and embedded pointers (from go1.10)
Every other field in a struct will be encoded/decoded.
Embedded fields are encoded as if they exist in the top-level struct,
with some caveats. See Encode documentation.

package codec
// Benefits of go-codec:
//
// - encoding/json always reads whole file into memory first.
// This makes it unsuitable for parsing very large files.
// - encoding/xml cannot parse into a map[string]interface{}
// I found this out on reading https://github.com/clbanning/mxj
// TODO:
// - For Go 1.11, when mid-stack inlining is enabled,
// we should use committed functions for writeXXX and readXXX calls.
// This involves uncommenting the methods for decReaderSwitch and encWriterSwitch
// and using those (decReaderSwitch and encWriterSwitch) in all handles
// instead of encWriter and decReader.
// The benefit is that, for the (En|De)coder over []byte, the encWriter/decReader
// will be inlined, giving a performance bump for that typical case.
// However, it will only be inlined if mid-stack inlining is enabled,
// as we call panic to raise errors, and panic currently prevents inlining.
//
// PUNTED:
// - To make Handle comparable, make extHandle in BasicHandle a non-embedded pointer,
// and use overlay methods on *BasicHandle to call through to extHandle after initializing
// the "xh *extHandle" to point to a real slice.
//
// BEFORE EACH RELEASE:
// - Look through and fix padding for each type, to eliminate false sharing
// - critical shared objects that are read many times
// TypeInfos
// - pooled objects:
// decNaked, decNakedContainers, codecFner, typeInfoLoadArray,
// - small objects allocated independently, that we read/use much across threads:
// codecFn, typeInfo
// - Objects allocated independently and used a lot
// Decoder, Encoder,
// xxxHandle, xxxEncDriver, xxxDecDriver (xxx = json, msgpack, cbor, binc, simple)
// - In all above, arrange values modified together to be close to each other.
//
// For all of these, either ensure that they occupy full cache lines,
// or ensure that the things just past the cache line boundary are hardly read/written
// e.g. JsonHandle.RawBytesExt - which is copied into json(En|De)cDriver at init
//
// Occupying full cache lines means they occupy 8*N words (where N is an integer).
// Check this out by running: ./run.sh -z
// - look at those tagged ****, meaning they are not occupying full cache lines
// - look at those tagged <<<<, meaning they are larger than 32 words (something to watch)
// - Run "golint -min_confidence 0.81"
// - optimization for codecgen:
// if len of entity is <= 3 words, then support a value receiver for encode.
// - (En|De)coder should store an error when it occurs.
// Until reset, subsequent calls return that error that was stored.
// This means that free panics must go away.
// All errors must be raised through errorf method.
// - Decoding using a chan is good, but incurs concurrency costs.
// This is because there's no fast way to use a channel without it
// having to switch goroutines constantly.
// Callback pattern is still the best. Maybe cnsider supporting something like:
// type X struct {
// Name string
// Ys []Y
// Ys chan <- Y
// Ys func(Y) -> call this function for each entry
// }
// - Consider adding a isZeroer interface { isZero() bool }
// It is used within isEmpty, for omitEmpty support.
// - Consider making Handle used AS-IS within the encoding/decoding session.
// This means that we don't cache Handle information within the (En|De)coder,
// except we really need it at Reset(...)
// - Consider adding math/big support
// - Consider reducing the size of the generated functions:
// Maybe use one loop, and put the conditionals in the loop.
// for ... { if cLen > 0 { if j == cLen { break } } else if dd.CheckBreak() { break } }

// EncodeTime encodes a time.Time as a []byte, including

//
// Format Description
//
// A timestamp is composed of 3 components:
//
// - secs: signed integer representing seconds since unix epoch
// - nsces: unsigned integer representing fractional seconds as a
// nanosecond offset within secs, in the range 0 <= nsecs < 1e9
// - tz: signed integer representing timezone offset in minutes east of UTC,
// and a dst (daylight savings time) flag
//
// When encoding a timestamp, the first byte is the descriptor, which
// defines which components are encoded and how many bytes are used to
// encode secs and nsecs components. *If secs/nsecs is 0 or tz is UTC, it
// is not encoded in the byte array explicitly*.
//
// Descriptor 8 bits are of the form `A B C DDD EE`:
// A: Is secs component encoded? 1 = true
// B: Is nsecs component encoded? 1 = true
// C: Is tz component encoded? 1 = true
// DDD: Number of extra bytes for secs (range 0-7).
// If A = 1, secs encoded in DDD+1 bytes.
// If A = 0, secs is not encoded, and is assumed to be 0.
// If A = 1, then we need at least 1 byte to encode secs.
// DDD says the number of extra bytes beyond that 1.
// E.g. if DDD=0, then secs is represented in 1 byte.
// if DDD=2, then secs is represented in 3 bytes.
// EE: Number of extra bytes for nsecs (range 0-3).
// If B = 1, nsecs encoded in EE+1 bytes (similar to secs/DDD above)
//
// Following the descriptor bytes, subsequent bytes are:
//
// secs component encoded in `DDD + 1` bytes (if A == 1)
// nsecs component encoded in `EE + 1` bytes (if B == 1)
// tz component encoded in 2 bytes (if C == 1)
//
// secs and nsecs components are integers encoded in a BigEndian
// 2-complement encoding format.
//
// tz component is encoded as 2 bytes (16 bits). Most significant bit 15 to
// Least significant bit 0 are described below:
//
// Timezone offset has a range of -12:00 to +14:00 (ie -720 to +840 minutes).
// Bit 15 = have\_dst: set to 1 if we set the dst flag.
// Bit 14 = dst\_on: set to 1 if dst is in effect at the time, or 0 if not.
// Bits 13..0 = timezone offset in minutes. It is a signed integer in Big Endian format.

// The advantage of fast paths is:
// - Many calls bypass reflection altogether
// - Many calls bypass reflection altogether
//
// Currently support
// - slice of all builtin types,
// - map of all builtin types to string or interface value
// - symmetrical maps of all builtin types (e.g. str-str, uint8-uint8)
// - slice of all builtin types,
// - map of all builtin types to string or interface value
// - symetrical maps of all builtin types (e.g. str-str, uint8-uint8)
// This should provide adequate "typical" implementations.
//
// Note that fast track decode functions must handle values for which an address cannot be obtained.
// For example:
// m2 := map[string]int{}
// p2 := []interface{}{m2}
// // decoding into p2 will bomb if fast track functions do not treat like unaddressable.
// m2 := map[string]int{}
// p2 := []interface{}{m2}

// Increase codecoverage by covering all the codecgen paths, in fast-path and gen-helper.go....
//
// Add:
// - test file for creating a mammoth generated file as _mammoth_generated.go
// - generate a second mammoth files in a different file: mammoth2_generated_test.go
// - mammoth-test.go.tmpl will do this
// - run codecgen on it, into mammoth2_codecgen_generated_test.go (no build tags)
// - as part of TestMammoth, run it also
// - this will cover all the codecgen, gen-helper, etc in one full run
// - check in mammoth* files into github also
// - then
//
// Now, add some types:
// - some that implement BinaryMarshal, TextMarshal, JSONMarshal, and one that implements none of it
// - create a wrapper type that includes TestMammoth2, with it in slices, and maps, and the custom types
// - this wrapper object is what we work encode/decode (so that the codecgen methods are called)
