Enum ttf_parser::tables::gvar::VariationTuples

enum VariationTuples<'a> {
    Stack {
        headers: [VariationTuple<'a>; 32],
        len: u16,
    },
}
Expand description

A list of variation tuples, possibly stored on the heap.

This is the only part of the gvar algorithm that actually allocates a data. This is probably unavoidable due to gvar structure, since we have to iterate all tuples in parallel.

Implementations§

source§

impl<'a> VariationTuples<'a>

source

fn reserve(&mut self, capacity: u16) -> bool

Attempt to reserve up to capacity total slots for variation tuples.

source

fn len(&self) -> u16

Get the number of tuples stored in the structure.

source

fn push(&mut self, header: VariationTuple<'a>)

Append a new tuple header to the list. This may panic if the list can’t hold a new header.

source

fn clear(&mut self)

Remove all tuples from the structure.

source

fn as_mut_slice(&mut self) -> &mut [VariationTuple<'a>]

source

fn apply( &mut self, all_points: GlyphPointsIter<'_>, points: GlyphPointsIter<'_>, point: GlyphPoint, ) -> Option<PointF>

source

fn apply_null(&mut self) -> Option<PointF>
