Struct errno::Errno

pub struct Errno(pub i32);

Wraps a platform-specific error code.

The Display instance maps the code to a human-readable string. It calls strerror_r under POSIX, and FormatMessageW on Windows.

Trait Implementations

impl Copy for Errno

impl Clone for Errno

fn clone(&self) -> Errno

Returns a copy of the value.

impl PartialOrd for Errno

fn partial_cmp(&self, __arg_0: &Errno) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &Errno) -> bool

This method tests less than (for self and other) and is used by the < operator.

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &Errno) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &Errno) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Hash for Errno

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].
