Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

impl Errno

source

pub fn last() -> Errno

source

pub fn desc(self) -> &'static str

source

pub const fn from_i32(err: i32) -> Errno
