Trait TypedCollectGlyphs 

pub trait TypedCollectGlyphs<T: LookupValue> {
    // Required method
    fn collect_glyphs_filtered<F>(
        &self,
        _set: &mut U32Set,
        _num_glyphs: u32,
        _filter: F,
    )
       where F: Fn(T) -> bool;

    // Provided method
    fn collect_glyphs(&self, set: &mut U32Set, num_glyphs: u32) { ... }
}

Required Methods

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

where 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(&self, set: &mut U32Set, num_glyphs: u32)

Add all indices into set.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
