phf 0.7.24

Compile-time generated maps and sets. The `phf::Map` and `phf::Set` types have roughly comparable performance to a standard hash table, but can be generated as compile-time static values. # Usage If the `macros` Cargo feature is enabled, the `phf_map`, `phf_set`, `phf_ordered_map`, and `phf_ordered_set` macros can be used to construct the PHF type. This currently requires a nightly compiler. ```toml [dependencies] phf = { version = "0.7.24", features = ["macros"] } ``` ``` #![feature(proc_macro_hygiene)] use phf::{phf_map, phf_set}; static MY_MAP: phf::Map<&'static str, u32> = phf_map! { "hello" => 1, "world" => 2, }; static MY_SET: phf::Set<&'static str> = phf_set! { "hello world", "hola mundo", }; fn main() { assert_eq!(MY_MAP["hello"], 1); assert!(MY_SET.contains("hello world")); } ``` Alternatively, you can use the phf_codegen crate to generate PHF datatypes in a build script. This method can be used with a stable compiler.
