Struct TimestampQueryPool 

pub struct TimestampQueryPool { /* private fields */ }

Timestamp query results associated with a completed fence.

Implementations

impl TimestampQueryPool

pub fn has_results(&self) -> bool

Returns true once the associated submission has completed.

A complete pool can still return None for a query when timestamps were unsupported, omitted, or never submitted.

pub fn duration(&self, query: TimestampQuery) -> Option<Duration>

Returns the duration from submission start to query, or None if results are not available.

None can mean the submission is still pending, timestamps were unsupported for the queue, or the query point was not part of submitted graph work. Use Self::has_results to distinguish pending work from a completed submission with no timestamp for this query.

When the checked feature is enabled, this panics if query belongs to a different graph.
