Implementations

impl Errno

pub fn into_raw(self) -> i32

Converts Errno into the under underlining integer.

pub fn is_valid(&self) -> bool

Returns true if the error code is in valid range (lower than 4096)

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

Returns a new Errno from a syscall’s result.

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