# icu_provider_registry [![crates.io](https://img.shields.io/crates/v/icu_provider_registry)](https://crates.io/crates/icu_provider_registry) Exposes the list of all known `DataMarker`s. This is modeled as a macro that accepts a callback macro of the shape: ```rust macro_rules! cb { ($($marker:path = $path:literal,)+ #[experimental] $($emarker:path = $epath:literal,)+) => { // Do something for each marker, or each experimental marker }; } ``` Calling this as `registry!(cb);` evaluates `cb` with the list of markers. ## More Information For more information on development, authorship, contributing etc. please visit [`ICU4X home page`](https://github.com/unicode-org/icu4x).
