Enum Event

#[non_exhaustive]
pub enum Event {
    Magnifier {
        active: WEnum<ActiveState>,
    },
    ScreenFilter {
        inverted: WEnum<ActiveState>,
        filter: WEnum<Filter>,
    },

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Magnifier

State of the screen magnifier

State of the screen magnifier.

This event will be emitted by the compositor when binding the protocol and whenever the state changes.

Fields

active: WEnum<ActiveState>

If the screen magnifier is enabled

ScreenFilter

State of screen filtering

Parameters used for screen filtering.

This event will be emitted by the compositor when binding the protocol and whenever the state changes.

If a screen filter is used not known to the protocol or the bound version filter will be set to unknown.

Since version 3 this event will not be emitted anymore, instead use screen_filter2.

Only available since version 2 of the interface

Fields

inverted: WEnum<ActiveState>

If the screen colors are inverted

filter: WEnum<Filter>

Which if any screen filter is enabled

ScreenFilter2

State of screen filtering

Parameters used for screen filtering.

This event will be emitted by the compositor when binding the protocol and whenever the state changes.

If a screen filter is used not known to the protocol or the bound version filter will be set to unknown.

The compositor must never send “disabled” as the “filter” argument.

Only available since version 3 of the interface

Fields

inverted: WEnum<ActiveState>

If the screen colors are inverted

filter: WEnum<Filter>

Which if any screen filter is selected

filter_state: WEnum<ActiveState>

If the screen filter is active
