Struct Reason 

pub struct Reason(pub u32);

reason for getting a session

The reason may determine in what way a session restores the window management state of associated toplevels.

For example newly launched applications might be launched on the active workspace with restored size and position, while a recovered application might restore additional state such as active workspace and stacking order.

Implementations

impl Reason

pub const Launch: Self

an app is newly launched

A new app instance is launched, for example from an app launcher.

pub const Recover: Self

an app recovered

An app instance is recovering from for example a compositor or app crash.

pub const SessionRestore: Self

an app restored

An app instance is restored, for example part of a restored session, or restored from having been temporarily terminated due to resource constraints.

impl Reason

pub fn available_since(self) -> Option<u32>

First protocol version enum variant is avilable in

None for unrecognized value.

Trait Implementations

impl Clone for Reason

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Reason

fn partial_cmp(&self, other: &Reason) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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