Struct capctl::Error

pub struct Error(_);

Represents an OS error encountered when performing an operation.

Note: Parsing errors (i.e. errors returned by FromStr implementations) have their own types; for example ParseCapError).

Implementations

impl Error

pub fn last() -> Self

Get the last OS error that occured (i.e. the current errno value).

pub fn from_code(eno: i32) -> Self

Construct an Error from an errno code.

pub fn code(&self) -> i32

Get the errno code represented by this Error object.
