Trait CollectGlyphs 

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

}

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".
