object Stopwatch extends Stopwatch

The system Stopwatch measures elapsed time using System.nanoTime.

Note that it works well with unit tests by respecting time manipulation on Time.

val systemMicros: () ⇒ Long

A function that returns a Long that can be used for measuring elapsed time in microseconds, using the system clock.
A function that returns a Long that can be used for measuring elapsed time in microseconds, using the system clock.
Note that invoking this doesn't entail any allocations.

A function that returns a Long that can be used for measuring elapsed time in milliseconds, using the system clock.
A function that returns a Long that can be used for measuring elapsed time in milliseconds, using the system clock.
Note that invoking this doesn't entail any allocations.
val systemNanos: () ⇒ Long

A function that returns a Long that can be used for measuring elapsed time in nanoseconds, using the system clock.
A function that returns a Long that can be used for measuring elapsed time in nanoseconds, using the system clock.
Note that invoking this doesn't entail any allocations.
val timeMicros: () ⇒ Long

A function that returns a Long that can be used for measuring elapsed time in microseconds, that is Time manipulation compatible.
A function that returns a Long that can be used for measuring elapsed time in microseconds, that is Time manipulation compatible.
Useful for testing, but should not be used in production, since it uses a non-monotonic time under the hood, and entails a few allocations. For production, see systemMicros.
