Struct ZwpInputTimestampsV1

pub struct ZwpInputTimestampsV1 { /* private fields */ }

Available on crate features unstable and server only.

context object for input timestamps

Provides high-resolution timestamp events for a set of subscribed input events. The set of subscribed input events is determined by the zwp_input_timestamps_manager_v1 request used to create this object.

See also the Request enum for this interface.

Implementations

impl ZwpInputTimestampsV1

pub fn timestamp(&self, tv_sec_hi: u32, tv_sec_lo: u32, tv_nsec: u32)

high-resolution timestamp event

The timestamp event is associated with the first subsequent input event carrying a timestamp which belongs to the set of input events this object is subscribed to.

The timestamp provided by this event is a high-resolution version of the timestamp argument of the associated input event. The provided timestamp is in the same clock domain and is at least as accurate as the associated input event timestamp.

The timestamp is expressed as tv_sec_hi, tv_sec_lo, tv_nsec triples, each component being an unsigned 32-bit value. Whole seconds are in tv_sec which is a 64-bit value combined from tv_sec_hi and tv_sec_lo, and the additional fractional part in tv_nsec as nanoseconds. Hence, for valid timestamps tv_nsec must be in [0, 999999999].

impl PartialEq<Weak<ZwpInputTimestampsV1>> for ZwpInputTimestampsV1

fn eq(&self, other: &Weak<ZwpInputTimestampsV1>) -> 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.
