Crate boot_time

Temporal quantification that takes into account the time a system spent suspended.

Note: Some systems like FreeBSD and AIX don’t support CLOCK_BOOTIME. For compatibility CLOCK_MONOTONIC is used as a fallback.

Examples

Using Instant to calculate how long a function took to run:

let now = Instant::now();

// Calling a slow function, it may take a while
slow_function();

let elapsed_time = now.elapsed();
println!("Running slow_function() took {} seconds.", elapsed_time.as_secs());

Structs

• Duration
  A Duration type to represent a span of time, typically used for system timeouts.
• Instant
  A measurement of a suspend-aware monotonically nondecreasing clock. Opaque and useful only with Duration.
