features

• feature-rich: supports reading and writing integers of varying sizes in both little and big endian
• performant: performs more than twice as fast as the standard library's bytes.Buffer
• simple and familiar: has a consistent and easy-to-use api
• licensed under the mpl-2.0: use it anywhere you wish, just don't change it privately

installation

install with the go tool

$ go get github.com/superwhiskers/crunch/v3

then, just import it in your project like this. easy!

package "yourpackage"

import crunch "github.com/superwhiskers/crunch/v3"

install using git submodules (not recommended)

# this assumes that you are in a git repository
$ git submodule add https://github.com/superwhiskers/crunch path/to/where/you/want/crunch

then, you can import it like this

package "yourpackage"

import crunch "github.com/your-username/project/path/to/crunch/v3"

benchmarks

both Buffer and MiniBuffer perform on average more than twice as fast as bytes.Buffer in both writing and reading
