Enum LanguageMatching 

#[non_exhaustive]
pub enum LanguageMatching {
    Lookup,
    BasicFilter,
}

How Accept-Language ranges are matched against offered tags.

Examples

use parse_net::negotiate::{LanguageMatching, Negotiator};

let offers = ["en-US"];
assert_eq!(Negotiator::new().language(Some(b"en"), &offers).index(), None);
let filter = Negotiator::new().language_matching(LanguageMatching::BasicFilter);
assert_eq!(filter.language(Some(b"en"), &offers).index(), Some(0));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Lookup

RFC 4647 section 3.4 lookup: a range matches an offer equal to it or reached by removing subtags from its end (en-US matches en).

BasicFilter

RFC 4647 section 3.3.1 basic filtering: a range matches an offer equal to it or starting with it and - (en matches en-US).
