Expand description

A helper trait to provide the functionality necessary to resources within a type.

This currently exists to abstract over TypeAlloc and SubtypeArena which both need to perform remapping operations.

Required Methods§

source

fn push_ty<T>(&mut self, ty: T) -> <T as TypeData>::Id
where T: TypeData,

Pushes a new anonymous type within this object, returning an identifier which can be used to refer to it.

Provided Methods§

source

fn map_map( tmp: &mut IndexMap<ResourceId, Vec<usize>>, any_changed: &mut bool, map: &Remapping, )

Apply map to the keys of tmp, setting *any_changed = true if any keys were remapped.

source

fn insert_if_any_changed<T>( &mut self, map: &mut Remapping, any_changed: bool, id: &mut <T as TypeData>::Id, ty: T, ) -> bool
where T: TypeData, <T as TypeData>::Id: Into<ComponentAnyTypeId>,

If any_changed is true, push ty, update map to point id to the new type ID, set id equal to the new type ID, and return true. Otherwise, update map to point id to itself and return false.
