Function unicode_bidi::explicit::compute

pub fn compute<'a, T: TextSource<'a> + ?Sized>(
    text: &'a T,
    para_level: Level,
    original_classes: &[BidiClass],
    levels: &mut [Level],
    processing_classes: &mut [BidiClass]
)

Compute explicit embedding levels for one paragraph of text (X1-X8).

processing_classes[i] must contain the BidiClass of the char at byte index i, for each char in text.
