pub fn name_and_description(&self) -> Option<(&'static str, &'static str)>

Returns a pair containing the name of the error and a string describing the error.

impl Errno

pub const EWOULDBLOCK: Self = Self::EAGAIN

Operation would block. This is the same as Errno::EAGAIN.

pub const EDEADLOCK: Self = Self::EDEADLK

Same as Errno::EDEADLK.

pub fn new(num: i32) -> Self

Creates a new Errno.

pub fn into_raw(self) -> i32

Converts the Errno into a raw i32.

pub fn is_valid(&self) -> bool

Returns true if the error code is valid (i.e., less than 4096).

pub fn from_ret(value: usize) -> Result<usize, Errno>

👎Deprecated: It is recommended to explicitly use u32 or u64.

Converts a raw syscall return value to a result.

Please use Errno::from_ret_u32 or Errno::from_ret_u64. Refactored Errno::from_ret to handle u32 and u64 explicitly, instead of using usize.

pub fn from_ret_u32(value: u32) -> Result<u32, Errno>

Rewriting of Errno::from_ret to use a u32 for pointer width. This function is for platforms where a pointer has a size of 32 bits.

pub fn from_ret_u64(value: u64) -> Result<u64, Errno>

Rewriting of Errno::from_ret to use a u64 for register width. This function is for platforms where the syscall return register is 64 bits.

pub fn last() -> Self

Returns the last error that occurred.

pub fn result<T>(value: T) -> Result<T, Errno>

where T: ErrnoSentinel + PartialEq<T>,

Converts a value into an Errno.

pub fn name(&self) -> Option<&'static str>

Returns the name of the error. If the internal error code is unknown or invalid, None is returned.

pub fn description(&self) -> Option<&'static str>

Returns the error description. If the internal error code is unknown or invalid, None is returned.

pub fn from_io_error(err: Error) -> Option<Self>

Converts an std::io::Error into an Errno if possible. Since an error code is just one of the few possible error types that std::io::Error can represent, this will return None if the conversion is not possible.

A From<std::io::Error> implementation is not provided because this conversion can fail. However, the reverse is possible, so that is provided as a From implementation.
