Enum SessionEvent 

#[non_exhaustive]
pub enum SessionEvent {
    Paused,
    Resumed {
        devices: Vec<TakenDevice>,
    },
}

What a caller needs to act on.

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.

Paused

Stop touching every device now.

The descriptors are about to stop working. Anything mapped from them has to be released by the caller – closing a descriptor does not unmap it, so a compositor that skips that leaks per switch.

Resumed

The devices are back, on new descriptors.

Every per-descriptor kernel object is gone: framebuffers, property blobs, client capabilities, GEM handles. All of it is rebuilt.

Fields

devices: Vec<TakenDevice>

The devices as they now stand, in the order they were taken.
