Enum Languages 

pub enum Languages {
    LocalLang = 0,
    English = 1,
}

Supported languages in the GUI framework.

This enum defines the available languages for internationalization. New languages can be added by extending this enum.

Variants

LocalLang = 0

Local language (default, typically Chinese)

English = 1

English language

Implementations

impl Languages

pub fn next(self) -> Self

Returns the next language in the sequence.

This method cycles through the available languages, returning the next language after the current one. It wraps around to the first language when reaching the end.

Returns

The next language in the sequence.

pub fn set_language(lang: Languages)

Sets the current language globally.

This method updates the global language selection using atomic operations. The change affects all subsequent string lookups throughout the application.

Arguments

• lang - The language to set as current.

pub fn get_language() -> Languages

Returns the currently selected language.

This method retrieves the current language selection from the atomic storage. The returned language determines which string variant is used for all internationalized strings.

Returns

The currently selected language.

pub fn switch_language()

Switches to the next language in the sequence.

This is a convenience method that combines get_language() and next() to cycle through available languages. It updates the global language selection to the next language in the sequence.

Trait Implementations

impl Clone for Languages

fn clone(&self) -> Languages

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Languages

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

Formats the value using the given formatter.

impl From<Languages> for &'static str

Conversion from Languages to a static string slice.

This implementation provides a human-readable name for each language. For LocalLang, it attempts to use the LOCAL_LANG_STRING environment variable at compile time, falling back to “中文” if not set.

fn from(lang: Languages) -> Self

Converts to this type from the input type.

impl From<u8> for Languages

Conversion from a byte index to Languages.

This implementation allows converting a language index (as stored in the atomic SELECTION variable) back to a Languages enum variant.

fn from(lang: u8) -> Self

Converts to this type from the input type.

impl PartialEq for Languages

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

impl Sequence for Languages

const CARDINALITY: usize

Number of values of type Self.

fn next(&self) -> Option<Self>

Returns value following *self or None if this was the end.

fn previous(&self) -> Option<Self>

Returns value preceding *self or None if this was the beginning.

fn first() -> Option<Self>

Returns the first value of type Self.

fn last() -> Option<Self>

Returns the last value of type Self.

impl Copy for Languages
