Module monotonic_clock

WASI Monotonic Clock is a clock API intended to let users measure elapsed time.

It is intended to be portable at least between Unix-family platforms and Windows.

A monotonic clock is a clock which has an unspecified initial value, and successive reads of the clock will produce non-decreasing values.

Functions

now

Read the current value of the clock.

resolution

Query the resolution of the clock. Returns the duration of time corresponding to a clock tick.

subscribe_duration

Create a pollable that will resolve after the specified duration has elapsed from the time this function is invoked.

subscribe_instant

Create a pollable which will resolve once the specified instant has occurred.

Type Aliases

Duration

A duration of time, in nanoseconds.

Instant

An instant in time, in nanoseconds. An instant is relative to an unspecified initial value, and can only be compared to instances from the same monotonic-clock.
