Possible imports into an adapter module.

Variants

CoreDef(CoreDef)

A definition required in the configuration of an Adapter.

Transcode

A transcoding function from the host to convert between string encodings.

Fields

op: Transcode

The transcoding operation this performs.

from: CoreDef

The memory being read

from64: bool

Whether or not from is a 64-bit memory

to: CoreDef

The memory being written

to64: bool

Whether or not to is a 64-bit memory

ResourceTransferOwn

Transfers an owned resource from one table to another.

ResourceTransferBorrow

Transfers a borrowed resource from one table to another.

ResourceEnterCall

Sets up entry metadata for a borrow resources when a call starts.

ResourceExitCall

Tears down a previous entry and handles checking borrow-related metadata.

PrepareCall

An intrinsic used by FACT-generated modules to begin a call involving an async-lowered import and/or an async-lifted export.

Fields

memory: Option<CoreDef>

The memory used to verify that the memory specified for the task.return that is called at runtime (if any) matches the one specified in the lifted export.

SyncStartCall

An intrinsic used by FACT-generated modules to complete a call involving a sync-lowered import and async-lifted export.

Fields

callback: Option<CoreDef>

The callee’s callback function, if any.

AsyncStartCall

An intrinsic used by FACT-generated modules to complete a call involving an async-lowered import function.

Fields

callback: Option<CoreDef>

The callee’s callback function, if any.

post_return: Option<CoreDef>

The callee’s post-return function, if any.

FutureTransfer

An intrinisic used by FACT-generated modules to (partially or entirely) transfer ownership of a future.

StreamTransfer

An intrinisic used by FACT-generated modules to (partially or entirely) transfer ownership of a stream.

ErrorContextTransfer

An intrinisic used by FACT-generated modules to (partially or entirely) transfer ownership of an error-context.

CheckBlocking

An intrinsic used by FACT-generated modules to check whether an async-typed function may be called via a sync lower.

Trap

An intrinsic for trapping the instance with a specific trap code.

Trait Implementations

impl Clone for Import

fn clone(&self) -> Import

Returns a duplicate of the value.

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

Performs copy-assignment from source.
