[][src]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[src]

pub fn as_errno(&self) -> Option<Errno>[src]

Convert this Error to an Errno.

Example

let e = Error::from(Errno::EPERM);
assert_eq!(Some(Errno::EPERM), e.as_errno());

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

Create a nix Error from a given errno

pub fn last() -> Error[src]

Get the current errno and convert it to a nix Error

pub fn invalid_argument() -> Error[src]

Create a new invalid argument error (EINVAL)
