Trait detone::IterDecomposeVietnamese

pub trait IterDecomposeVietnamese<I: Iterator<Item = char>> {
    // Required method
    fn decompose_vietnamese_tones(
        self,
        orthographic: bool,
    ) -> DecomposeVietnamese<I> ;
}

Trait that adds a decompose_vietnamese_tones method to iterators over char.

Required Methods

fn decompose_vietnamese_tones( self, orthographic: bool, ) -> DecomposeVietnamese<I>

Assuming that self is an iterator yielding a sequence of chars in Normalization Form C (this precondition is not checked!), yields a sequence of chars with Vietnamese tone marks less or more decomposed. Note that the output is not in Unicode Normalization Form D or any Normalization Form. Circumflex and breve are not detached from their base characters.

If orthographic is false, tone marks are decomposed if there is no precomposed form form the incoming character in windows-1258. E.g. á is not decomposed, but ý is decomposed to y followed by combining acute and ấ is decomposed to â followed by combining acute.

If orthographic is true, tone marks are always decomposed. That is, even á is decomposed.
