Enum Event

#[non_exhaustive]
pub enum Event {
    Timestamp {
        tv_sec_hi: u32,
        tv_sec_lo: u32,
        tv_nsec: u32,
    },
}

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.

Timestamp

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].

Fields

tv_sec_hi: u32

high 32 bits of the seconds part of the timestamp

tv_sec_lo: u32

low 32 bits of the seconds part of the timestamp

tv_nsec: u32

nanoseconds part of the timestamp
