Type Alias nix::Error

source ·

pub type Error = Errno;

Expand description

Nix’s main error type.

It’s a wrapper around Errno. As such, it’s very interoperable with std::io::Error, but it has the advantages of:

Clone
Copy
Eq
Small size
Represents all of the system’s errnos, instead of just the most common ones.

Implementations§

source §

impl Errno

source

pub const EWOULDBLOCK: Errno = Errno::EAGAIN

source

pub const EDEADLOCK: Errno = Errno::EDEADLK

source

pub const ENOTSUP: Errno = Errno::EOPNOTSUPP

source §

impl Errno

source

pub fn last() -> Self

Returns the current value of errno

source

pub fn last_raw() -> i32

Returns the current raw i32 value of errno

source

pub fn set(self)

Sets the value of errno.

Example

use nix::errno::Errno;

Errno::EIO.set();

assert_eq!(Errno::last(), Errno::EIO);

source

pub fn set_raw(errno: i32)

Sets the raw i32 value of errno.

source

pub const fn from_i32(err: i32) -> Errno

👎Deprecated since 0.28.0: please use Errno::from_raw() instead

source

pub const fn from_raw(err: i32) -> Errno

source

pub fn desc(self) -> &'static str

source

pub fn clear()

Sets the platform-specific errno to no-error

use nix::errno::Errno;

Errno::EIO.set();

Errno::clear();

let err = Errno::last();
assert_ne!(err, Errno::EIO);
assert_eq!(err, Errno::from_raw(0));
