Enum DrawMemory 

pub enum DrawMemory<'a> {
    Scratch,
    Buffer(&'a mut [u8]),
}

Working memory for drawing an outline.

A glyf outline and a VARC composite need working memory to draw; a charstring needs none. The size an outline needs is given by its required_memory_size.

Variants

Scratch

Short-lived scratch memory of the size the outline needs, which may be allocated on the heap for a large glyph.

Buffer(&'a mut [u8])

Memory supplied by the caller, of at least the size the outline needs.
