A “Linker” object, that is used to match functions with module imports during instantiation. Cloning is a cheap operation for this object. All clones refer to the same data in store.

Required Methods

fn new(store: &mut <WB as WasmBackend>::Store) -> Self

Creates a new empty object.

fn insert( &mut self, store: &impl AsContext<WB>, module: impl Into<String>, name: impl Into<String>, func: <WB as WasmBackend>::HostFunction ) -> Result<(), ImportError>

Inserts a function with name name to the namespace module.

Errors:

An error returned if such combination of `module` and `name` already has an associated function.

fn register<S, I>( &mut self, store: &impl AsContext<WB>, name: S, namespace: I ) -> Result<(), ImportError>

where S: Into<String>, I: IntoIterator<Item = (String, <WB as WasmBackend>::HostFunction)>,

Inserts several named functions to the same namespace module at once, an equivalent to multiple calls of insert.

Errors:

An error returned if such combination of `module` and `name` already has an associated function.

Object Safety

This trait is not object safe.
