It's part of Project Fluent, a localization framework designed to unleash +//! the expressive power of the natural language. +//! +//! The primary use of fluent-langneg is to parse/modify/serialize language tags +//! and to perform language negotiation. +//! +//! fluent-langneg operates on a subset of [BCP47](http://tools.ietf.org/html/bcp47). +//! It can parse full BCP47 language tags, and will serialize them back, +//! but currently only allows for operations on primary subtags and +//! unicode extension keys. +//! +//! In result fluent-langneg is not suited to replace full implementations of +//! BCP47 like [rust-language-tags](https://github.com/pyfisch/rust-language-tags), +//! but is arguably a better option for use cases involving operations on +//! language tags and for language negotiation. + +pub mod accepted_languages; +pub mod negotiate; + +pub use accepted_languages::parse as parse_accepted_languages; +pub use negotiate::negotiate_languages; +pub use negotiate::NegotiationStrategy; + +use unic_langid::{LanguageIdentifier, LanguageIdentifierError}; + +pub fn convert_vec_str_to_langids<'a, I, J>( + input: I, +) -> Result, LanguageIdentifierError> +where + I: IntoIterator, + J: AsRef<[u8]> + 'a, +{ + input + .into_iter() + .map(|s| LanguageIdentifier::from_bytes(s.as_ref())) + .collect() +} + +pub fn convert_vec_str_to_langids_lossy<'a, I, J>(input: I) -> Vec +where + I: IntoIterator, + J: AsRef<[u8]> + 'a, +{ + input + .into_iter() + .filter_map(|t| LanguageIdentifier::from_bytes(t.as_ref()).ok()) + .collect() +} -- cgit v1.2.3
