Struct Errno

pub struct Errno(/* private fields */);

errno—An error code.

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.

Implementations

impl Errno

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

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

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

pub const fn raw_os_error(self) -> i32

Extract the raw OS error number from this error.

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

Construct an Errno from a raw OS error number.

impl Errno

pub fn kind(self) -> ErrorKind

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

Trait Implementations

impl Clone for Errno

fn clone(&self) -> Errno

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Errno

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Errno

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Errno

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Errno> for Error

fn from(err: Errno) -> Self

Converts to this type from the input type.

impl Hash for Errno

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Errno

fn eq(&self, other: &Errno) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
