# go-mangler
|
||||
|
||||
[Documentation](https://pkg.go.dev/codeberg.org/gruf/go-mangler).
|
||||
|
||||
To put it simply is a bit of an odd library. It aims to provide incredibly fast, unique string outputs for all default supported input data types during a given runtime instance.
|
||||
|
||||
It is useful, for example, for use as part of larger abstractions involving hashmaps. That was my particular usecase anyways...
|
||||
|
||||
This package does make liberal use of the "unsafe" package.
|
||||
|
||||
Benchmarks are below. Those with missing values panicked during our set of benchmarks, usually a case of not handling nil values elegantly. Please note the more important thing to notice here is the relative difference in benchmark scores, the actual `ns/op`,`B/op`,`allocs/op` accounts for running through over 80 possible test cases, including some not-ideal situations.
|
||||
|
||||
The choice of libraries in the benchmark are just a selection of libraries that could be used in a similar manner to this one, i.e. serializing in some manner.

This package is a port of the [xxh3](https://github.com/Cyan4973/xxHash) library to Go.
|

|

Upstream has fixed the output as of v0.8.0, and this package matches that.
