Trait tracing_tree::time::FormatTime

pub trait FormatTime {
    // Required method
    fn format_time(&self, w: &mut impl Write) -> Result;
}

A type that can measure and format the current time.

This trait is used by HierarchicalLayer to include a timestamp with each Event when it is logged.

Notable default implementations of this trait are [LocalDateTime] and (). The former prints the current time as reported by time’s OffsetDateTime (note that it requires a time feature to be enabled and may panic! make sure to check out the docs for the [LocalDateTime]), and the latter does not print the current time at all.

Inspired by the FormatTime trait from tracing-subscriber.
