Implementations

impl Lang

pub fn detect() -> Self

Detect the locale from LC_ALL, then LC_MESSAGES, then LANG. A value starting with zh (case-insensitive, e.g. zh_CN.UTF-8, zh-Hans, zh_TW) maps to Lang::Zh. Everything else falls back to English.

pub fn parse_arg(s: &str) -> Self

Parse the value passed via --lang. Accepts en, english, zh, zh-cn, zh_cn, cn, chinese (case-insensitive). Unknown values fall back to Lang::En — the user’s intent is “show me something”, not “abort because of a typo”.

pub fn strings(self) -> &'static Strings

Return the static label table for this language.

Trait Implementations

impl Clone for Lang

fn clone(&self) -> Lang

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Lang

impl Debug for Lang

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

Formats the value using the given formatter.

impl Default for Lang

fn default() -> Lang

Returns the “default value” for a type.

impl Eq for Lang

impl PartialEq for Lang

fn eq(&self, other: &Lang) -> 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.
