Struct os_error::OsError

pub struct OsError { /* fields omitted */ }

Methods

impl OsError

fn new(code: i32) -> OsError

Creates a new instance of an OsError from a particular OS error code.

Examples

On Linux:

use std::io;

let error = os_error::OsError::new(98);
assert_eq!(error.kind(), io::ErrorKind::AddrInUse);

On Windows:

use std::io;

let error = os_error::OsError::new(10048);
assert_eq!(error.kind(), io::ErrorKind::AddrInUse);

fn last_os_error() -> OsError

Returns an error representing the last OS error which occurred.

This function reads the value of errno for the target platform (e.g. GetLastError on Windows) and will return a corresponding instance of OsError for the error code.

Examples

use os_error::OsError;

println!("last OS error: {:?}", OsError::last_os_error());

fn code(&self) -> i32

Returns the OS error that this error represents.

Examples

use os_error::OsError;

fn main() {
    // Will print "raw OS error: ...".
    println!("raw OS error: {:?}", OsError::last_os_error().code());
}

fn kind(&self) -> ErrorKind

Returns the corresponding ErrorKind for this error.

Examples

use os_error::OsError;

fn main() {
    // Will print "No inner error".
    println!("{:?}", OsError::last_os_error());
}
