Struct RangeIter 

struct RangeIter<'a, T> {
    ranges: Iter<'a, T>,
    num_glyphs: u32,
    gid: u32,
    first: u32,
    end: u32,
    prev_end: u32,
}

Custom iterator for range based formats.

Each individual lookup requires a linear scan through the ranges so this provides a more efficient code path for iteration.

Fields

ranges: Iter<'a, T>

num_glyphs: u32

gid: u32

first: u32

end: u32

prev_end: u32

Implementations

impl<'a, T> RangeIter<'a, T>

where T: CharsetRange,

fn new(ranges: &'a [T], num_glyphs: u32) -> Self

fn next(&mut self) -> Option<(GlyphId, StringId)>

Trait Implementations

impl<'a, T: Clone> Clone for RangeIter<'a, T>

fn clone(&self) -> RangeIter<'a, T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
