impl Errno
sourcepub fn from_io_error(io_err: &Error) -> Option<Self>
pub fn from_io_error(io_err: &Error) -> Option<Self>
Extract an Errno
value from a std::io::Error
.
This isn’t a From
conversion because it’s expected to be relatively
uncommon.
sourcepub const fn raw_os_error(self) -> i32
pub const fn raw_os_error(self) -> i32
Extract the raw OS error number from this error.
sourcepub const fn from_raw_os_error(raw: i32) -> Self
pub const fn from_raw_os_error(raw: i32) -> Self
Construct an Errno
from a raw OS error number.
