Implementations

impl ModuleGlobals

pub fn add_import( &mut self, ty: ValType, mutable: bool, import_id: ImportId ) -> GlobalId

Adds a new imported global to this list.

pub fn add_local( &mut self, ty: ValType, mutable: bool, init: InitExpr ) -> GlobalId

Construct a new global, that does not originate from any of the input wasm globals.

pub fn get(&self, id: GlobalId) -> &Global

Gets a reference to a memory given its id

pub fn get_mut(&mut self, id: GlobalId) -> &mut Global

Gets a reference to a memory given its id

pub fn delete(&mut self, id: GlobalId)

Removes a global from this module.

It is up to you to ensure that any potential references to the deleted global are also removed, eg get_global expressions.

Get a shared reference to this module’s globals.
