Struct AcceptLanguage 

pub struct AcceptLanguage(pub Vec<String>);

A client’s language preferences, from Accept-Language: tags in the order to try them (highest q first, then header order), lower-cased. Ranges with q=0 are left out; * is kept as "*".

Tuple Fields

0: Vec<String>

Implementations

impl AcceptLanguage

pub fn parse(value: &str) -> AcceptLanguage

Parse an Accept-Language value. Never fails: malformed entries are skipped.

pub fn from_request(request: &Request) -> AcceptLanguage

The request’s preferences (empty without the header).

pub fn negotiate<'a>(&self, available: &[&'a str]) -> Option<&'a str>

The best of available for these preferences (RFC 4647 lookup: each range as is, then with subtags removed from the end; then a range’s language matching an available regional tag — en gets en-GB), or None. * matches nothing in particular, so the caller’s default applies.
