Struct wit_bindgen::Resource

pub struct Resource<T: WasmResource> { /* private fields */ }

A type which represents a component model resource, either imported or exported into this component.

This is a low-level wrapper which handles the lifetime of the resource (namely this has a destructor). The T provided defines the component model intrinsics that this wrapper uses.

One of the chief purposes of this type is to provide Deref implementations to access the underlying data when it is owned.

This type is primarily used in generated code for exported and imported resources.

Implementations

impl<T: WasmResource> Resource<T>

pub fn new(val: T) -> Resource<T>

where T: RustResource,

Creates a new Rust-defined resource from the underlying representation T.

This will move T onto the heap to create a single pointer to represent it which is then wrapped up in a component model resource.

pub fn into_inner(resource: Self) -> T

where T: RustResource,

Takes back ownership of the object, dropping the resource handle.

Trait Implementations

impl<T: WasmResource> Debug for Resource<T>

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

Formats the value using the given formatter.

impl<T: RustResource> Deref for Resource<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: RustResource> DerefMut for Resource<T>

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.

impl<T: WasmResource> Drop for Resource<T>

fn drop(&mut self)

Executes the destructor for this type.
