Struct linux_errno::Error
source · pub struct Error(/* private fields */);
Expand description
Type for error numbers returned from Linux system calls.
The Error
type implements PartialEq
for many integer types, and
(optionally) with the POSIX error numbers defined in the posix-errno
library.
Implementations§
source§impl Error
impl Error
sourcepub const fn new(errno: u16) -> Option<Error>
pub const fn new(errno: u16) -> Option<Error>
Create a new error from a raw error number. If outside the permitted
range [1, 4096)
for Linux error numbers, returns None
.
sourcepub const unsafe fn new_unchecked(errno: u16) -> Error
pub const unsafe fn new_unchecked(errno: u16) -> Error
Unsafely create a new error from a raw error number, without checking whether it’s within the permitted range for Linux error numbers.
§Safety
The caller must ensure that 0 < errno <= 0xFFF
. In particular, it is
undefined behavior if errno
is zero.
sourcepub const fn get_nonzero(&self) -> NonZeroU16
pub const fn get_nonzero(&self) -> NonZeroU16
Returns the error number as a NonZeroU16
.
