Available on crate feature __ecma and (crate features __ecma_transforms or __testing_transform) only.

Required Associated Constants

const RESET_N: bool

Should reset n to 0 for each identifier?

const MANGLE: bool

It should be true if you expect lots of collisions

Required Methods

fn new_name_for(&self, orig: &(Atom, SyntaxContext), n: &mut usize) -> Atom

Should increment n.

Provided Methods

fn preserved_ids_for_module( &mut self, _: &Module, ) -> HashSet<(Atom, SyntaxContext), BuildHasherDefault<FxHasher>>

fn preserved_ids_for_script( &mut self, _: &Script, ) -> HashSet<(Atom, SyntaxContext), BuildHasherDefault<FxHasher>>

fn get_cached( &self, ) -> Option<Cow<'_, HashMap<(Atom, SyntaxContext), Atom, BuildHasherDefault<FxHasher>>>>

fn store_cache( &mut self, _update: &HashMap<(Atom, SyntaxContext), Atom, BuildHasherDefault<FxHasher>>, )

Object Safety

This trait is not object safe.
