Enum HandlerError 

pub enum HandlerError {
    MissingMessageType,
    Unsupported(MessageType),
    Custom(String),
}

The message header did not contain a valid message type.

Unsupported(MessageType)

The agent does not handle the message type.

Custom(String)

Custom handler error with human-readable context.

Implementations

impl HandlerError

pub fn custom(reason: impl Into<String>) -> Self

Creates a custom error variant from a string-like value.

Trait Implementations

impl Debug for HandlerError

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

Formats the value using the given formatter.

impl Display for HandlerError

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

Formats the value using the given formatter.

impl Error for HandlerError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for HandlerError

fn eq(&self, other: &HandlerError) -> 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.
