rasa/monotonic

Monotonic time and unique integer generation backed by Erlang’s monotonic_time/1 and unique_integer/1.

Types

TimeUnit

The time unit used to convert the current erlang monotonic time. Passed directly to erlang’s monotonic_time/1.

pub type TimeUnit {
  Second
  Millisecond
  Microsecond
  Nanosecond
  Native
}

Constructors

```
Second
```
Monotonic time in seconds.
```
Millisecond
```
Monotonic time in milliseconds.
```
Microsecond
```
Monotonic time in microseconds.
```
Nanosecond
```
Monotonic time in nanoseconds.
```
Native
```
Native time unit used by the erlang runtime system.

Values

time

</>

pub fn time(unit: TimeUnit) -> Int

Returns the current monotonic time in the given TimeUnit. Note that consecutive calls may return the same value, especially with coarser time units like Second or Millisecond.

unique

</>

pub fn unique() -> Int

Returns a unique integer that is monotonically ordered. Consecutive calls are guaranteed to produce strictly increasing values, unlike time which may return the same value from consecutive calls. Backed by erlang’s unique_integer/1. These are strictly monotonically increasing integers which are expensive to generate.
