Struct rustix::io::Error

source · [−]

#[repr(transparent)]
pub struct Error(_);

Expand description

The error type for rustix APIs.

This is similar to std::io::Error, but only holds an OS error code, and no extra error value.

impl Error

source

pub fn from_io_error(io_err: &Error) -> Option<Self>

Extract an Error value from a std::io::Error.

This isn’t a From conversion because it’s expected to be relatively uncommon.

source

pub const fn raw_os_error(self) -> i32

Extract the raw OS error number from this error.

source

pub const fn from_raw_os_error(raw: i32) -> Self

Construct an Error from a raw OS error number.

source

impl Error

source

pub fn kind(self) -> ErrorKind

Shorthand for std::io::Error::from(self).kind().
