Possible imports that can be passed to Resolve::wasm_import_name.

Variants

Func

A WIT function is being imported. Optionally from an interface.

Fields

interface: Option<&'a WorldKey>

The name of the interface that the function is being imported from.

If the function is imported directly from the world then this is None.

func: &'a Function

The function being imported.

ResourceIntrinsic

A resource-related intrinsic is being imported.

Fields

interface: Option<&'a WorldKey>

The optional interface to import from, same as WasmImport::Func.

resource: Id<TypeDef>

The resource that’s being operated on.

intrinsic: ResourceIntrinsic

The intrinsic that’s being imported.

FutureIntrinsic

A future-related intrinsic is being imported.

Fields

interface: Option<&'a WorldKey>

The optional interface to import from, same as WasmImport::Func.

func: &'a Function

The function whose signature this future type appears in.

ty: Option<Id<TypeDef>>

The future type appearing in func.find_futures_and_streams(resolve).

Use None for the special unit payload case.

intrinsic: FutureIntrinsic

The intrinsic that’s being imported.

exported: bool

Whether this import is for an exported WIT function.

This controls whether the module name is prefixed with [export].

async_: bool

Whether this intrinsic import is async-lowered.

This is only valid for read/write/cancel intrinsics.

StreamIntrinsic

A stream-related intrinsic is being imported.

Fields

interface: Option<&'a WorldKey>

The optional interface to import from, same as WasmImport::Func.

func: &'a Function

The function whose signature this stream type appears in.

ty: Option<Id<TypeDef>>

The stream type appearing in func.find_futures_and_streams(resolve).

Use None for the special unit payload case.

intrinsic: StreamIntrinsic

The intrinsic that’s being imported.

exported: bool

Whether this import is for an exported WIT function.

This controls whether the module name is prefixed with [export].

async_: bool

Whether this intrinsic import is async-lowered.

This is only valid for read/write/cancel intrinsics.

Trait Implementations

impl<'a> Debug for WasmImport<'a>

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

Formats the value using the given formatter.
