Trait CollectGlyphs 

pub trait CollectGlyphs {
    // Required method
    fn collect_glyphs_filtered<T, F>(
        &self,
        _set: &mut U32Set,
        _num_glyphs: u32,

Required Methods

fn collect_glyphs_filtered<T, F>( &self, _set: &mut U32Set, _num_glyphs: u32, _filter: F, )

where T: LookupValue, F: Fn(T) -> bool,

For each valid index, read the value of type T. If filter(&value) returns true, insert the index into set.

Provided Methods

fn collect_glyphs<T>(&self, set: &mut U32Set, num_glyphs: u32)

where T: LookupValue,

Add all indices into set.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
