Enum ErrorCode

#[non_exhaustive]
pub enum ErrorCode<E: HandlerCode = u8> {
    SystemCode(SystemCode),
    HandlerCode(E),
    Unknown(u16),
}

Error and success codes returned by the message API.

Variants (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.

SystemCode(SystemCode)

A known system error code.

HandlerCode(E)

A custom error code returned by a handler.

Unknown(u16)

Unknown error code.

Trait Implementations

impl<E: Clone + HandlerCode> Clone for ErrorCode<E>

fn clone(&self) -> ErrorCode<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Debug + HandlerCode> Debug for ErrorCode<E>

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

Formats the value using the given formatter.

impl<E: HandlerCode> From<u16> for ErrorCode<E>

fn from(value: u16) -> Self

Converts to this type from the input type.

impl<E: HandlerCode> Into<u16> for ErrorCode<E>

fn into(self) -> u16

Converts this type into the (usually inferred) input type.

impl<E: HandlerCode> PartialEq for ErrorCode<E>

fn eq(&self, other: &Self) -> 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<E: Copy + HandlerCode> Copy for ErrorCode<E>

impl<E: HandlerCode> Eq for ErrorCode<E>
