pathtrie

A specialised trie for paths in the style of a Patricia or radix trie, with optional optimised FST output.

The intended usage of this data structure is for optimally storing and querying keys that have a large number of shared prefixes, such as file paths in a file system.

This crate is partly inspired by the fst crate by Andrew Gallant. There are a few significant differences to that crate, however:

• Simplicity of implementation was prioritised over speed
• The trie structure is mutable and can be later written into an FST
• Insertions do not need to be in lexicographical order

It is a goal of this project to stabilise the FST format once proven to be bug-free.

Usage
