Implementations

impl Errno[−]

pub fn last() -> Self

pub fn desc(self) -> &'static str

pub fn from_i32(err: i32) -> Errno

pub unsafe fn clear()

pub fn result<S: ErrnoSentinel + PartialEq<S>>(value: S) -> Result<S>[−]

Returns Ok(value) if it does not contain the sentinel value. This should not be used when -1 is not the errno sentinel value.

Trait Implementations

impl Clone for Errno[+]

[+] Show hidden undocumented items

fn clone(&self) -> Errno[−]

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.

impl Copy for Errno

impl Debug for Errno[+]

[+] Show hidden undocumented items

fn fmt(&self, f: &mut Formatter) -> Result[−]

Formats the value using the given formatter.

impl Display for Errno[+]

[+] Show hidden undocumented items

fn fmt(&self, f: &mut Formatter) -> Result[−]

Formats the value using the given formatter.

impl Eq for Errno

impl Error for Errno[+]

[+] Show hidden undocumented items

fn description(&self) -> &str[−]

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

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

fn backtrace(&self) -> Option<&Backtrace>[−]

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

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

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Errno> for Error[+]

[+] Show hidden undocumented items

fn from(err: Errno) -> Self[−]

Performs the conversion.

impl From<Errno> for Error[+]

[+] Show hidden undocumented items

fn from(errno: Errno) -> Error[−]

Performs the conversion.

impl PartialEq<Errno> for Errno[+]

[+] Show hidden undocumented items

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

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

[+] Expand attributes

#[must_use]fn ne(&self, other: &Rhs) -> bool[−]

This method tests for !=.
