Unsafe zero-copy slice casts for Go

Convenience functions for casting raw bytes to typed arrays without copying.

Usage:

b := []byte{1, 2, 3, 4}
v := unsafeslice.Uint32SliceFromByteSlice(b)

Documentation ¶

Overview ¶

Package unsafeslice contains functions for zero-copy casting between typed slices and byte slices.

func ByteSliceFromFloat32Slice ¶ added in v0.3.0

func ByteSliceFromFloat32Slice(b []float32) []byte

func ByteSliceFromFloat64Slice ¶ added in v0.3.0

func ByteSliceFromFloat64Slice(b []float64) []byte

func ByteSliceFromInt16Slice ¶

func ByteSliceFromInt16Slice(b []int16) []byte

func ByteSliceFromInt32Slice ¶

func ByteSliceFromInt32Slice(b []int32) []byte

func ByteSliceFromInt64Slice ¶

func ByteSliceFromInt64Slice(b []int64) []byte

func ByteSliceFromInt8Slice ¶

func ByteSliceFromInt8Slice(b []int8) []byte

func ByteSliceFromString ¶

func ByteSliceFromString(s string) []byte

func ByteSliceFromStructSlice ¶

func ByteSliceFromStructSlice(s interface{}) []byte

ByteSliceFromStructSlice does what you would expect.

Note that this is slower than the scalar primitives above as it uses reflection.

func ByteSliceFromUint16Slice ¶

func ByteSliceFromUint16Slice(b []uint16) []byte

func ByteSliceFromUint32Slice ¶

func ByteSliceFromUint32Slice(b []uint32) []byte

func ByteSliceFromUint64Slice ¶

func ByteSliceFromUint64Slice(b []uint64) []byte

func ByteSliceFromUint8Slice ¶ added in v0.2.0

func ByteSliceFromUint8Slice(b []uint8) []byte

func Float32SliceFromByteSlice ¶ added in v0.3.0

func Float32SliceFromByteSlice(b []byte) []float32

func Float64SliceFromByteSlice ¶ added in v0.3.0

func Float64SliceFromByteSlice(b []byte) []float64

func Int16SliceFromByteSlice ¶

func Int16SliceFromByteSlice(b []byte) []int16

func Int32SliceFromByteSlice ¶

func Int32SliceFromByteSlice(b []byte) []int32

func Int64SliceFromByteSlice ¶

func Int64SliceFromByteSlice(b []byte) []int64

func Int8SliceFromByteSlice ¶

func Int8SliceFromByteSlice(b []byte) []int8

func StringFromByteSlice ¶

func StringFromByteSlice(b []byte) string

func StructSliceFromByteSlice ¶

func StructSliceFromByteSlice(b []byte, out interface{})

Create a slice of structs from a slice of bytes.

var v []Struct
StructSliceFromByteSlice(bytes, &v)

Elements in the byte array must be padded correctly. See unsafe.AlignOf, et al.

Note that this is slower than the scalar primitives above as it uses reflection.

func Uint16SliceFromByteSlice ¶

func Uint16SliceFromByteSlice(b []byte) []uint16

func Uint32SliceFromByteSlice ¶

func Uint32SliceFromByteSlice(b []byte) []uint32

func Uint64SliceFromByteSlice ¶

func Uint64SliceFromByteSlice(b []byte) []uint64

func Uint8SliceFromByteSlice ¶ added in v0.2.0

func Uint8SliceFromByteSlice(b []byte) []uint8
