Struct uapi::Errno

pub struct Errno(pub c_int);

c_int newtype which wraps ERRNO values

The Default implementation returns the current value of ERRNO.

Trait Implementations

impl Clone for Errno

pub fn clone(&self) -> Errno

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Errno

impl Debug for Errno

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

Formats the value using the given formatter.

impl Default for Errno

pub fn default() -> Self

Returns the "default value" for a type.

impl Display for Errno

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

impl Eq for Errno

impl Error for Errno

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Errno> for Error

pub fn from(e: Errno) -> Self

Performs the conversion.

impl PartialEq<Errno> for Errno

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
