-struc
-====
-
-Struc exists to pack and unpack C-style structures from bytes, which is useful for binary files and network protocols. It could be considered an alternative to `encoding/binary`, which requires massive boilerplate for some similar operations.
-
-Take a look at an [example comparing `struc` and `encoding/binary`](https://bochs.info/p/cxvm9)
-
-Struc considers usability first. That said, it does cache reflection data and aims to be competitive with `encoding/binary` struct packing in every way, including performance.
-
-Example struct
-----
-
-```Go
-type Example struct {
- Var int `struc:"int32,sizeof=Str"`
- Str string
- Weird []byte `struc:"[8]int64"`
- Var []int `struc:"[]int32,little"`
-}
-```
-
-Struct tag format
-----
-
- - ```Var []int `struc:"[]int32,little,sizeof=StringField"` ``` will pack Var as a slice of little-endian int32, and link it as the size of `StringField`.
- - `sizeof=`: Indicates this field is a number used to track the length of a another field. `sizeof` fields are automatically updated on `Pack()` based on the current length of the tracked field, and are used to size the target field during `Unpack()`.
- - Bare values will be parsed as type and endianness.
-
-Endian formats
-----
-
- - `big` (default)
- - `little`
-
-Recognized types
-----
-
- - `pad` - this type ignores field contents and is backed by a `[length]byte` containing nulls
- - `bool`
- - `byte`
- - `int8`, `uint8`
- - `int16`, `uint16`
- - `int32`, `uint32`
- - `int64`, `uint64`
- - `float32`
- - `float64`
-
-Types can be indicated as arrays/slices using `[]` syntax. Example: `[]int64`, `[8]int32`.
-
-Bare slice types (those with no `[size]`) must have a linked `Sizeof` field.
-
-Private fields are ignored when packing and unpacking.
-
-Example code
-----
-
-```Go
-package main
-
-import (
- "bytes"
- "github.com/lunixbochs/struc"
-)
-
-type Example struct {
- A int `struc:"big"`
-
- // B will be encoded/decoded as a 16-bit int (a "short")
- // but is stored as a native int in the struct
- B int `struc:"int16"`
-
- // the sizeof key links a buffer's size to any int field
- Size int `struc:"int8,little,sizeof=Str"`
- Str string
-
- // you can get freaky if you want
- Str2 string `struc:"[5]int64"`
-}
-
-func main() {
- var buf bytes.Buffer
- t := &Example{1, 2, 0, "test", "test2"}
- err := struc.Pack(&buf, t)
- o := &Example{}
- err = struc.Unpack(&buf, o)
-}
-```
-
-Benchmark
-----
-
-`BenchmarkEncode` uses struc. `Stdlib` benchmarks use equivalent `encoding/binary` code. `Manual` encodes without any reflection, and should be considered an upper bound on performance (which generated code based on struc definitions should be able to achieve).
-
-```
-BenchmarkEncode 1000000 1265 ns/op
-BenchmarkStdlibEncode 1000000 1855 ns/op
-BenchmarkManualEncode 5000000 284 ns/op
-BenchmarkDecode 1000000 1259 ns/op
-BenchmarkStdlibDecode 1000000 1656 ns/op
-BenchmarkManualDecode 20000000 89.0 ns/op
