std::time::SystemTimeError - Rust
Description: API documentation for the Rust `SystemTimeError` struct in crate `std`.
Keywords: rust, rustlang, rust-lang, SystemTimeError

# 1.8.0[−][src]Struct std::time::SystemTimeError

    pub struct SystemTimeError(_);

An error returned from the `duration_since` and `elapsed` methods on `SystemTime`, used to learn how far in the opposite direction a system time lies.

# Examples

    use std::thread::sleep;
    use std::time::{Duration, SystemTime};

    let sys_time = SystemTime::now();
    sleep(Duration::from_secs(1));
    let new_sys_time = SystemTime::now();
    match sys_time.duration_since(new_sys_time) {
        Ok(_) => {}
        Err(e) => println!("SystemTimeError difference: {:?}", e.duration()),
    }Run

## Methods

###

`impl SystemTimeError`

[src]

####

`pub fn duration(&self) -> Duration`

[src]

Returns the positive duration which represents how far forward the second system time was from the first.

A `SystemTimeError` is returned from the `duration_since` and `elapsed` methods of `SystemTime` whenever the second system time represents a point later in time than the `self` of the method call.

# Examples

    use std::thread::sleep;
    use std::time::{Duration, SystemTime};

    let sys_time = SystemTime::now();
    sleep(Duration::from_secs(1));
    let new_sys_time = SystemTime::now();
    match sys_time.duration_since(new_sys_time) {
        Ok(_) => {}
        Err(e) => println!("SystemTimeError difference: {:?}", e.duration()),
    }Run

## 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`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
