Struct wasmtime::Export

source · [−]

pub struct Export<'instance> { /* private fields */ }

Expand description

An exported WebAssembly value.

This type is primarily accessed from the Instance::exports accessor and describes what names and items are exported from a wasm instance.

Implementations

source

impl<'instance> Export<'instance>

source

pub fn name(&self) -> &'instance str

Returns the name by which this export is known.

source

pub fn ty(&self, store: impl AsContext) -> ExternType

Return the ExternType of this export.

Panics

Panics if store does not own this Extern.

source

pub fn into_extern(self) -> Extern

Consume this Export and return the contained Extern.

source

pub fn into_func(self) -> Option<Func>

Consume this Export and return the contained Func, if it’s a function, or None otherwise.

source

pub fn into_table(self) -> Option<Table>

Consume this Export and return the contained Table, if it’s a table, or None otherwise.

source

pub fn into_memory(self) -> Option<Memory>

Consume this Export and return the contained Memory, if it’s a memory, or None otherwise.

source

pub fn into_global(self) -> Option<Global>

Consume this Export and return the contained Global, if it’s a global, or None otherwise.
