FastBytes
FastBytes is a go package for translating between slices with fixed-size integers/floats and byte slices.
Supported Types
Floats and all signed/unsigned integers except uint and int can be translated by this package.
uint and int are not supported since their size is platform dependent.
Usage
Usage of assembly code
This package uses assembly for copying data on certain platforms.
To disable the usage of assembly set the purego build tag when building.
Usage of unsafe.Pointer
This package uses the unsafe package to covert between slice/array types and to extract pointers from interface{} values. To disable the usage of unsafe set the no_unsafe build tag when building. Note that this also disables the usage of assembly.
