Crate simple_interner [−] [src]
A very simplistic interner based around giving out (wrapped) references
rather than some placeholder symbol. This means that e.g. strings can be interned in systems
based around &str without rewriting to support a new Symbol type.
The typical use case for something like this is text processing chunks, where chunks are very
likely to be repeated. For example, when parsing source code, identifiers are likely to come up
multiple times. Rather than have a Token::Identifier(String) and allocate every occurrence of
those identifiers separately, interners allow you to store Token::Identifier(Symbol), and
compare identifier equality by the interned symbol.
This crate exists to give the option of using a simplistic interface. If you want or need further power, there are multiple other options available on crates.io.
