Enum nix::Error

pub enum Error {
    Sys(Errno),
    InvalidPath,
    InvalidUtf8,
    UnsupportedOperation,
}

Nix Error Type

The nix error type provides a common way of dealing with various system system/libc calls that might fail. Each error has a corresponding errno (usually the one from the underlying OS) to which it can be mapped in addition to implementing other common traits.

Variants

Sys(Errno)InvalidPathInvalidUtf8

The operation involved a conversion to Rust's native String type, which failed because the string did not contain all valid UTF-8.

UnsupportedOperation

The operation is not supported by Nix, in this instance either use the libc bindings or consult the module documentation to see if there is a more appropriate interface available.

Methods

impl Error

pub fn from_errno(errno: Errno) -> Error

Create a nix Error from a given errno

pub fn last() -> Error

Get the current errno and convert it to a nix Error

pub fn invalid_argument() -> Error

Create a new invalid argument error (EINVAL)

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&Error>
