Trait wayland_protocols::unstable::input_timestamps::v1::client::zwp_input_timestamps_v1::EventHandler

pub trait EventHandler {
    fn timestamp(
        &mut self, 
        object: ZwpInputTimestampsV1, 
        tv_sec_hi: u32, 
        tv_sec_lo: u32, 
        tv_nsec: u32
    ) { ... }
}

An interface for handling events.

Provided methods

fn timestamp(
    &mut self,
    object: ZwpInputTimestampsV1,
    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].
