Required Methods

fn resolve(&self, font: &Font, database: &mut Arc<Database>) -> Option<ID>

Attempt to resolve a font reference using the provided database of fonts. Adding new fonts to the database is allowed. Return an index into the database if the font resolves to an entry, otherwise return None.

fn resolve_fallback( &self, char: char, excluded: &[ID], database: &mut Arc<Database>, ) -> Option<ID>

Backup resolve. Find a font that can represent char and is not in excluded.

Dyn Compatibility

This trait is dyn compatible.

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