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)InvalidPath

Methods

impl Error

fn from_errno(errno: Errno) -> Error[−]

Create a nix Error from a given errno

fn last() -> Error[−]

Get the current errno and convert it to a nix Error

fn invalid_argument() -> Error[−]

Create a new invalid argument error (EINVAL)

fn errno(&self) -> Errno[−]

Get the errno associated with this error

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, __arg_0: &mut Formatter) -> Result[−]

Formats the value using the given formatter.

impl PartialEq for Error

fn eq(&self, __arg_0: &Error) -> bool[−]

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Error) -> bool[−]

This method tests for !=.

impl From<Errno> for Error

fn from(errno: Errno) -> Error[−]

Performs the conversion.

impl Error for Error

fn description(&self) -> &str[−]

A short description of the error.

fn cause(&self) -> Option<&Error>[−]

The lower-level cause of this error, if any.

impl Display for Error

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

Formats the value using the given formatter.
