Enum DispatchError 

pub enum DispatchError {
    UnknownAggregateType(String),
    UnknownCommand,
    Deserialization(Error),
    Execution(Box<dyn Error + Send + Sync>),
    Io(Error),
}

Errors that can occur when dispatching a command.

Produced by the dispatch layer (CommandBus or process manager dispatch) when a command cannot be routed to or executed by the target aggregate.

Variants

UnknownAggregateType(String)

No dispatcher registered for the target aggregate type.

UnknownCommand

No route registered for the command type.

Returned by CommandBus::dispatch when the command’s concrete type has not been registered via register::<A>().

Deserialization(Error)

The command JSON could not be deserialized into the target aggregate’s command type.

Execution(Box<dyn Error + Send + Sync>)

The target aggregate’s command handler rejected the command or an I/O error occurred during execution.

Io(Error)

An I/O error occurred during dispatch (e.g. directory creation).

Trait Implementations

impl Debug for DispatchError

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

Formats the value using the given formatter.

impl Display for DispatchError

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

Formats the value using the given formatter.

impl Error for DispatchError

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 From<Error> for DispatchError

fn from(source: Error) -> Self

Converts to this type from the input type.
