}

Represents an active driver mapping session.

Variants

Close

Terminates the connection.

After calling Close, the client must not send any other requests.

Servers, after sending the status response, should close the connection regardless of status and without sending an epitaph.

Closing the client end of the channel should be semantically equivalent to calling Close without knowing when the close has completed or its status.

Fields

responder: MapperSessionCloseResponder

CreateVmo

Creates a pager-backed VMO of size bytes associated with key. Page faults on this VMO are handled directly by the driver mapper.

Fields

key: u64

size: u64

options: CreateVmoOptions

responder: MapperSessionCreateVmoResponder

OpenChildSession

Opens a child mapper session whose reads map through parent_key in the parent session. When a parent session is closed, all child sessions opened from it are closed as well.

Fields

session: ServerEnd<MapperSessionMarker>

mapping_vmo: Vmo

parent_key: u64

port: Option<Port>

delivery_queue: Option<Vmo>

responder: MapperSessionOpenChildSessionResponder

#[non_exhaustive]

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: MapperSessionControlHandle

method_type: MethodType
