Struct LocaleChain 

pub struct LocaleChain(/* private fields */);

Ordered locale fallback chain.

Implementations

impl LocaleChain

pub fn from_tags(tags: Vec<LocaleTag>) -> LocaleChain

Builds a locale chain and appends global fallback when absent.

pub fn from_cli(raw: &str) -> Result<LocaleChain, LocaleError>

Parses a comma-separated CLI locale chain.

pub fn merge_policy_and_cli( policy: Option<&[LocaleTag]>, cli: Option<&[LocaleTag]>, ) -> LocaleChain

Merges policy and CLI locale preferences.

pub fn merge_cli_policy_rulepack_default( cli: Option<&[LocaleTag]>, policy: Option<&[LocaleTag]>, rulepack_defaults: Option<&[LocaleTag]>, ) -> LocaleChain

Merges CLI, policy, rulepack, and default locale preferences.

pub fn intersects(&self, recognizer_locales: &[LocaleTag]) -> bool

Returns true when a recognizer can run under this locale chain.

pub fn as_slice(&self) -> &[LocaleTag]

Returns the locale tags in chain order.

pub fn to_strings(&self) -> Vec<String>

Returns the locale chain as canonical strings.

Trait Implementations

impl Clone for LocaleChain

fn clone(&self) -> LocaleChain

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LocaleChain

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<&[LocaleTag]> for LocaleChain

fn from(tags: &[LocaleTag]) -> LocaleChain

Converts to this type from the input type.

impl PartialEq for LocaleChain

fn eq(&self, other: &LocaleChain) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
