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. See mangler.String()for supported types.
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. 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 ~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.
