Struct icu::locale::fallback::LocaleFallbackIterator

pub struct LocaleFallbackIterator<'a, 'b> { /* private fields */ }

Iteration type for locale fallback operations.

Because the Iterator trait does not allow items to borrow from the iterator, this class does not implement that trait. Instead, use .step() and .get().

Implementations

impl LocaleFallbackIterator<'_, '_>

pub fn get(&self) -> &DataLocale

Borrows the current DataLocale under fallback.

pub fn take(self) -> DataLocale

Takes the current DataLocale under fallback.

pub fn step(&mut self) -> &mut LocaleFallbackIterator<'_, '_>

Performs one step of the locale fallback algorithm.

The fallback is completed once the inner DataLocale becomes DataLocale::default().

Trait Implementations

impl<'a, 'b> Debug for LocaleFallbackIterator<'a, 'b>

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

Formats the value using the given formatter.
