BenchmarkClock

Conformances

• protocol Clock<Duration>

  A mechanism in which to measure time, and delay work until a given point in time.

• protocol Copyable

  A type whose values can be implicitly or explicitly copied.

• protocol Escapable
• protocol Sendable

Types

• struct Instant

  A continuous point in time used for BenchmarkClock.

Type members

• init()
• static var now: BenchmarkClock.Instant

  The current continuous instant.

Instance members

• var minimumResolution: Swift.Duration

  The minimum non-zero resolution between any two calls to now.

• var now: BenchmarkClock.Instant

  The current continuous instant.

• func sleep(until: Instant, tolerance: Swift.Duration?) async throws

  Suspend task execution until a given deadline within a tolerance. If no tolerance is specified then the system may adjust the deadline to coalesce CPU wake-ups to more efficiently process the wake-ups in a more power efficient manner.

Type features

• static var internalUTC: BenchmarkClock

  A clock that measures time that always increments but does not stop incrementing while the system is asleep.

Instance features

• func measure(() throws -> Void) rethrows -> Self.Instant.Duration

  Measure the elapsed time to execute a closure.

• func measure(isolation: isolated (any Actor)?, () async throws -> Void) async rethrows -> Self.Instant.Duration

  Measure the elapsed time to execute an asynchronous closure.

• func sleep(for: Self.Instant.Duration, tolerance: Self.Instant.Duration?) async throws

  Suspends for the given duration.
