pub struct Error(_);

An error number, retrieved from errno (man 3 errno), set by a libc function that returned an error.

Methods

impl Error

pub fn new(e: i32) -> Error

Constructs a new error with the given errno.

pub fn last() -> Error

Constructs an error from the current errno.

The result of this only has any meaning just after a libc call that returned a value indicating errno was set.

pub fn errno(&self) -> i32

Gets the errno for this error
