Struct wasmtime_environ::component::CoreExport

pub struct CoreExport<T> {
    pub instance: RuntimeInstanceIndex,
    pub item: ExportItem<T>,
}

Identifier of an exported item from a core WebAssembly module instance.

Note that the T here is the index type for exports which can be identified by index. The T is monomorphized with types like EntityIndex or FuncIndex.

Fields

instance: RuntimeInstanceIndex

The instance that this item is located within.

Note that this is intended to index the instances map within a component. It’s validated ahead of time that all instance pointers refer only to previously-created instances.

item: ExportItem<T>

The item that this export is referencing, either by name or by index.

Implementations

impl<T> CoreExport<T>

pub fn map_index<U>(self, f: impl FnOnce(T) -> U) -> CoreExport<U>

Maps the index type T to another type U if this export item indeed refers to an index T.

Trait Implementations

impl<T: Clone> Clone for CoreExport<T>

fn clone(&self) -> CoreExport<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for CoreExport<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for CoreExport<T>

where T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<CoreExport<T>> for CoreDef

where EntityIndex: From<T>,

fn from(export: CoreExport<T>) -> CoreDef

Converts to this type from the input type.

impl<T: Hash> Hash for CoreExport<T>

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<T: PartialEq> PartialEq for CoreExport<T>

fn eq(&self, other: &CoreExport<T>) -> 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.

impl<T> Serialize for CoreExport<T>

where T: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
