Required Methods§

Source

fn now<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Datetime>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Read the current value of the clock.

This clock is not monotonic, therefore calling this function repeatedly will not necessarily produce a sequence of non-decreasing values.

The returned timestamps represent the number of seconds since 1970-01-01T00:00:00Z, also known as POSIX’s Seconds Since the Epoch, also known as Unix Time.

The nanoseconds field of the output is always less than 1000000000.

Source

fn resolution<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Datetime>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Query the resolution of the clock.

The nanoseconds field of the output is always less than 1000000000.
