Expand description

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.
