Struct XxSessionManagerV1

pub struct XxSessionManagerV1 { /* private fields */ }

Available on crate feature wayland and Linux only.

manage sessions for applications

The xx_session_manager interface defines base requests for creating and managing a session for an application. Sessions persist across application and compositor restarts unless explicitly destroyed. A session is created for the purpose of maintaining an application’s xdg_toplevel surfaces across compositor or application restarts. The compositor should remember as many states as possible for surfaces in a given session, but there is no requirement for which states must be remembered.

This interface has no events.

Implementations

impl XxSessionManagerV1

pub fn destroy(&self)

Destroy this object

This has no effect other than to destroy the xx_session_manager object.

pub fn get_session<U, D>( &self, reason: Reason, session: Option<String>, qh: &QueueHandle<D>, udata: U, ) -> XxSessionV1

where U: Send + Sync + 'static, D: Dispatch<XxSessionV1, U> + 'static,

create or restore a session

Create a session object corresponding to either an existing session identified by the given session identifier string or a new session. While the session object exists, the session is considered to be “in use”.

If a identifier string represents a session that is currently actively in use by the the same client, an ‘in_use’ error is raised. If some other client is currently using the same session, the new session will replace managing the associated state.

NULL is passed to initiate a new session. If an id is passed which does not represent a valid session, the compositor treats it as if NULL had been passed.

A client is allowed to have any number of in use sessions at the same time.

Trait Implementations

impl Borrow<ObjectId> for XxSessionManagerV1

fn borrow(&self) -> &ObjectId

Immutably borrows from an owned value.

impl Clone for XxSessionManagerV1

fn clone(&self) -> XxSessionManagerV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for XxSessionManagerV1

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

Formats the value using the given formatter.

impl Hash for XxSessionManagerV1

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

impl PartialEq<Weak<XxSessionManagerV1>> for XxSessionManagerV1

fn eq(&self, other: &Weak<XxSessionManagerV1>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
