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)

Tuple Fields

0: Errno

InvalidPath

InvalidUtf8

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.

Implementations

Convert this Error to an Errno.

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

Create a nix Error from a given errno

Get the current errno and convert it to a nix Error

Create a new invalid argument error (EINVAL)
