Struct ResourceType

pub struct ResourceType { /* private fields */ }

Describes the type of a resource. This may either be:

• An abstract guest resource, associated with a component. Abstract resources cannot be used to instantiate any values.
• An instantiated guest resource, associated with an instance. Instantiated guest resources identify resources created by WASM.
• A host resource, which is associated with a native value.

Implementations

impl ResourceType

pub fn new<T: 'static + Send + Sync + Sized>( name: Option<TypeIdentifier>, ) -> Self

Creates a new host resource for storing values of the given type. Note that multiple resource types may be created for the same T, and they will be distinct.

pub fn with_destructor<T: 'static + Send + Sync + Sized, C: AsContextMut>( ctx: C, name: Option<TypeIdentifier>, destructor: impl 'static + Send + Sync + Fn(StoreContextMut<'_, C::UserState, C::Engine>, T) -> Result<()>, ) -> Result<Self>

Creates a new host resource for storing values of the given type. Additionally, adds a destructor that is called when the resource is dropped. Note that multiple resource types may be created for the same T, and they will be distinct.

pub fn name(&self) -> Option<&TypeIdentifier>

Gets the name of this type, if any.

Trait Implementations

impl Clone for ResourceType

fn clone(&self) -> ResourceType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ResourceType

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

Formats the value using the given formatter.

impl Hash for ResourceType

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ResourceType

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
