Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations§

source §

impl Errno

source

pub const EWOULDBLOCK: Errno = Errno::EAGAIN

source

pub const EDEADLOCK: Errno = Errno::EDEADLK

source

pub const ENOTSUP: Errno = Errno::EOPNOTSUPP

source §

impl Errno

source

pub const 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());

source

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

source

pub const fn invalid_argument() -> Error

👎Deprecated since 0.22.0: Use Errno::EINVAL instead

Create a new invalid argument error (EINVAL)

source

pub fn last() -> Self

source

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

source

pub const fn from_i32(err: i32) -> Errno

source

pub fn clear()

source

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.

source

pub const 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.
