Struct QueryParamResolver 

pub struct QueryParamResolver { /* private fields */ }

Resolves the active locale from a URL query parameter.

When available_locales is non-empty, only values present in that list are accepted. An empty slice means “accept any value” — the resolver returns whatever string the request carried. See LocaleResolver for how this differs from AcceptLanguageResolver.

Implementations

impl QueryParamResolver

pub fn new(param_name: &str, available_locales: &[String]) -> Self

Creates a new resolver that looks at param_name in the query string.

available_locales constrains which values are accepted; pass &[] to accept all values.

Trait Implementations

impl LocaleResolver for QueryParamResolver

fn resolve(&self, parts: &Parts) -> Option<String>

Returns a locale string (e.g. "en", "uk") if this resolver can determine the locale from the request, or None to fall through to the next resolver.
