# Function std::thread::sleep 1.4.0 [−] [src]

    pub fn sleep(dur: Duration)

Puts the current thread to sleep for the specified amount of time.

The thread may sleep longer than the duration specified due to scheduling specifics or platform-dependent functionality.

# Platform behavior

On Unix platforms this function will not return early due to a signal being received or a spurious wakeup. Platforms which do not support nanosecond precision for sleeping will have `dur` rounded up to the nearest granularity of time they can sleep for.

# Examples

fn main() { use std::{thread, time}; let ten_millis = time::Duration::from_millis(10); let now = time::Instant::now(); thread::sleep(ten_millis); assert!(now.elapsed() >= ten_millis); }

    use std::{thread, time};

    let ten_millis = time::Duration::from_millis(10);
    let now = time::Instant::now();

    thread::sleep(ten_millis);

    assert!(now.elapsed() >= ten_millis);

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
