Implementations

impl Errno

pub const ELAST: Errno

pub const EWOULDBLOCK: Errno

pub const EDEADLOCK: Errno

pub const EOPNOTSUPP: Errno

impl Errno

pub fn as_errno(self) -> Option<Self>

👎 Deprecated since 0.22.0:

It’s a no-op now; just delete it.

Convert this Error to an Errno.

Example

let e = Error::from(Errno::EPERM);
assert_eq!(Some(Errno::EPERM), e.as_errno());

pub fn from_errno(errno: Errno) -> Error

👎 Deprecated since 0.22.0:

It’s a no-op now; just delete it.

Create a nix Error from a given errno

pub fn invalid_argument() -> Error

👎 Deprecated since 0.22.0:

Use Errno::EINVAL instead

Create a new invalid argument error (EINVAL)

pub fn last() -> Self

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

pub fn from_i32(err: i32) -> Errno

pub 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.

pub fn Sys(errno: Errno) -> Error

👎 Deprecated since 0.22.0:

Use Errno::… instead

Backwards compatibility hack for Nix <= 0.21.0 users

In older versions of Nix, Error::Sys was an enum variant. Now it’s a function, which is compatible with most of the former use cases of the enum variant. But you should use Error(Errno::...) instead.

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)>

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 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

impl From<Errno> for Error

fn from(err: Errno) -> Self

Performs the conversion.

impl PartialEq<Errno> for Errno

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

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

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

This method tests for !=.

impl TryFrom<Error> for Errno

type Error = Error

The type returned in the event of a conversion error.

fn try_from(ioerror: Error) -> Result<Self, Error>

Performs the conversion.
