pub const MAX: Self

From MAX_ERRNO in include/linux/err.h in kernel source. This doesn’t seem to be exposed in the installed kernel headers from which we generate bindings. https://github.com/torvalds/linux/blob/a4d7d701121981e3c3fe69ade376fe9f26324161/include/linux/err.h#L18

pub const fn from_u16(val: u16) -> Option<Self>

pub const fn to_negated_i64(self) -> i64

For C interop.

pub const fn to_negated_i32(self) -> i32

For C interop.

pub fn from_libc_errno() -> Self

Get libc’s errno (global for the current thread).

pub fn result_from_libc_errno<T>(sentinel: T, x: T) -> Result<T, Self>

where T: Eq,

Get a Result from the return value of a libc function that uses a sentinel error value, and stores the errors themselves in errno.

pub fn result_from_libc_errnum(errnum: i32) -> Result<(), Self>

Get a Result from a libc errnum return value, where 0 is used to indicate “no error”, and non-zero is an errno value. An example of such a function is libc::posix_spawn.

Panics if errnum is out of range. This shouldn’t be the case for any errnum obtained from libc APIs.

pub fn from_libc_errnum(errnum: i32) -> Option<Self>

Convert from a libc error value. Returns None if out of range.

Trait Implementations

impl Clone for Errno

fn clone(&self) -> Errno

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Errno

impl Debug for Errno

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

Formats the value using the given formatter.

impl Display for Errno

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

Formats the value using the given formatter.

impl Eq for Errno

impl Error for Errno

Available on crate feature std only.

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 u16

fn from(val: Errno) -> u16

Converts to this type from the input type.

impl From<Errno> for u32

fn from(val: Errno) -> u32

Converts to this type from the input type.

impl From<Errno> for u64

fn from(val: Errno) -> u64

Converts to this type from the input type.

impl From<Errno> for i32

fn from(val: Errno) -> i32

Converts to this type from the input type.

impl From<Errno> for i64

fn from(val: Errno) -> i64

Converts to this type from the input type.

impl From<Errno> for Error

Available on crate feature std only.

fn from(e: Errno) -> Self

Converts to this type from the input type.

impl From<Error> for Errno

fn from(value: Error) -> Self

Converts to this type from the input type.

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.
