# 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.

# go-structr
A performant struct caching library with automated indexing by arbitrary combinations of fields, including support for negative results (errors!). An example use case is in database lookups.
A library with a series of performant data types with automated struct value indexing. Indexing is supported via arbitrary combinations of fields, and in the case of the cache type, negative results (errors!) are also supported.
Under the hood, go-structr maintains a hashmap per index, where each hashmap is a hashmap keyed with either 32bit, 48bit or 64bit (default) hash checksum of the inputted raw index keys. The hash checksum size can be controlled by the following Go build-tags: `structr_32bit_hash` `structr_48bit_hash`
Under the hood, go-structr maintains a hashmap per index, where each hashmap is a hashmap keyed by serialized input key type. This is handled by the incredibly performant serialization library [go-mangler](https://codeberg.org/gruf/go-mangler), which at this point in time supports just about **any** arbitrary type, so feel free to index by *anything*!
