Trait Implementations

impl Clone for ErrNo

fn clone(&self) -> ErrNo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ErrNo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Error> for ErrNo

fn from(err: Error) -> Self

Converts to this type from the input type.

impl PartialEq for ErrNo

fn eq(&self, other: &ErrNo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<u16> for ErrNo

type Error = ()

The type returned in the event of a conversion error.

fn try_from(prim: u16) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<u8> for ErrNo

type Error = ()

The type returned in the event of a conversion error.

fn try_from(prim: u8) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for ErrNo

impl Eq for ErrNo

impl StructuralPartialEq for ErrNo
