Struct wasm_component_layer::Linker

pub struct Linker { /* private fields */ }

Provides the ability to define imports for a component and create Instances of it.

Implementations

impl Linker

pub fn root(&self) -> &LinkerInstance

Immutably obtains the root interface for this linker.

pub fn root_mut(&mut self) -> &mut LinkerInstance

Mutably obtains the root interface for this linker.

pub fn define_instance( &mut self, name: InterfaceIdentifier ) -> Result<&mut LinkerInstance>

Creates a new instance in the linker with the provided name. Returns an error if an instance with that name already exists.

pub fn instance(&self, name: &InterfaceIdentifier) -> Option<&LinkerInstance>

Immutably obtains the instance with the given name, if any.

pub fn instance_mut( &mut self, name: &InterfaceIdentifier ) -> Option<&mut LinkerInstance>

Mutably obtains the instance with the given name, if any.

pub fn instances( &self ) -> impl ExactSizeIterator<Item = (&InterfaceIdentifier, &LinkerInstance)>

Gets an immutable iterator over all instances defined in this linker.

pub fn instances_mut( &mut self ) -> impl ExactSizeIterator<Item = (&InterfaceIdentifier, &mut LinkerInstance)>

Gets a mutable iterator over all instances defined in this linker.

pub fn instantiate( &self, ctx: impl AsContextMut, component: &Component ) -> Result<Instance>

Instantiates a component for the provided store, filling in its imports with externals defined in this linker. All imports must be defined for instantiation to succeed.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Linker

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
