Struct smithay::wayland::explicit_synchronization::ExplicitSyncState

pub struct ExplicitSyncState {
    pub acquire: Option<RawFd>,
    pub release: Option<ExplicitBufferRelease>,
}

An explicit synchronization state

The client is not required to fill both. acquire being None means that you don’t need to wait before accessing the buffer, release being None means that the client does not require additional signaling that you are finished (you still need to send wl_buffer.release).

When processing the current state, Option::take the values from it. Otherwise they’ll be treated as unused and released when overwritten by the next client commit.

Fields

acquire: Option<RawFd>

An acquire dma_fence object, that you should wait on before accessing the contents of the buffer associated with the surface.

release: Option<ExplicitBufferRelease>

A buffer release object, that you should use to signal the client when you are done using the buffer associated with the surface.
