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.

Destroy

destroy the object and unregister the brightness control device

This is a destructor, once received this object cannot be used any longer.

SetInternal

sets whether or not the brightness device belongs to an internal display

Fields

internal: u32

1 if it’s an internal panel, 0 if not

SetEdid

set the EDID data for identification of the display

Fields

string: String

base-64 encoded string of the first 128 bytes of the EDID

SetMaxBrightness

notifies the compositor of the maximum brightness that can be set on this device

Fields

value: u32

the maximum value that can be set

Commit

notifies the compositor that all relevant identifiers and values have been sent

SetObservedBrightness

notifies the compositor of the brightness that was read from this device

The client can set this to notify the compositor of the device’s initial brightness. It can also set this again after the initial commit to notify the compositor that the brightness level has changed due to external factors. The compositor is free to use or ignore this value as it sees fit.

Only available since version 2 of the interface

Fields

value: u32

the observed value that was read
