Struct spa_meta_sync_timeline

#[repr(C)]
pub struct spa_meta_sync_timeline {
    pub flags: u32,
    pub padding: u32,
    pub acquire_point: u64,
    pub release_point: u64,
}

A timeline point for explicit sync

Metadata to describe the time on the timeline when the buffer can be acquired and when it can be reused.

This metadata will require negotiation of 2 extra fds for the acquire and release timelines respectively. One way to achieve this is to place this metadata as SPA_PARAM_BUFFERS_metaType when negotiating a buffer layout with 2 extra fds.

Fields

flags: u32

padding: u32

acquire_point: u64

< the timeline acquire point, this is when the data can be accessed.

release_point: u64

< the timeline release point, this timeline point should be signaled when the data is no longer accessed.

Trait Implementations

impl Clone for spa_meta_sync_timeline

fn clone(&self) -> spa_meta_sync_timeline

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for spa_meta_sync_timeline

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl PartialEq for spa_meta_sync_timeline

fn eq(&self, other: &spa_meta_sync_timeline) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
