Trait Implementations

impl Clone for ReturnCode

fn clone(&self) -> ReturnCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ReturnCode

impl Debug for ReturnCode

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

Formats the value using the given formatter.

impl Eq for ReturnCode

impl From<ReturnCode> for u8

fn from(value: ReturnCode) -> Self

Converts a ReturnCode into a u8 value.

impl PartialEq for ReturnCode

fn eq(&self, other: &ReturnCode) -> 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 StructuralPartialEq for ReturnCode

impl TryFrom<u8> for ReturnCode

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

Converts a u8 value into a ReturnCode.

type Error = Error

The type returned in the event of a conversion error.
