Struct ScratchLengths 

struct ScratchLengths {
    stack: usize,
    cvt: usize,
    storage: usize,
    twilight: usize,
}

The working memory a glyph program needs beyond the outline.

Fields

stack: usize

cvt: usize

storage: usize

twilight: usize

Implementations

impl ScratchLengths

fn packed_len(&self, points: usize) -> usize

Returns the bytes a block needs for carve to succeed with an outline of points points.

fn carve<'a>(&self, buf: &'a mut [u8], points: usize) -> Option<HintScratch<'a>>

Splits buf into the slices a glyph program uses.

Returns None if buf is shorter than packed_len.

Trait Implementations

impl Clone for ScratchLengths

fn clone(&self) -> ScratchLengths

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ScratchLengths

impl Default for ScratchLengths

fn default() -> ScratchLengths

Returns the “default value” for a type.
