Enum Request

#[non_exhaustive]
pub enum Request<'a> {
    MirrorHead {
        head: ZwlrOutputHeadV1,
        mirroring: ZwlrOutputHeadV1,
    },
    Release,
}

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.

MirrorHead

enable and configure a head to mirror another head

Enable a head mirroring another.

This request creates a head configuration object that can be used to change the head’s properties.

This is an alternative to zwlr_output_configuration_v1::enable_head or zwlr_output_configuration_v1::disable_head Using either with the same head argument will result in an already_configured_head error on the original zwlr_output_configuration_v1 object.

All properties are still required to be set to the resulting zwlr_output_configuration_head by the client as denoted in the original protocol. Some like set_position however might be ignored in mirroring configurations.

Trying to set a disabled or mirroring head as mirroring or calling disable_head/mirror_head after using a head as a mirroring argument will raise a mirrored_head_busy protocol error.

Fields

head: ZwlrOutputHeadV1

the head to be enabled

mirroring: ZwlrOutputHeadV1

the head to be mirrored

Release

destroy the output configuration

Using this request a client can tell the compositor that it is not going to use the configuration object anymore. Any changes to the outputs will still be attached to the original zwlr_output_configuration_head_v1 if it isn’t destroyed.

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