Struct MachineError 

pub struct MachineError<A, M, E> {
    pub event: User<A, M>,
    pub cause: E,
}

Controlled machine rejection with the complete unaccepted mailbox input.

Fields

event: User<A, M>

Exact user event whose transition or induced drain was rejected.

cause: E

Domain error returned by the phase function.

Trait Implementations

impl<A: Clone, M: Clone, E: Clone> Clone for MachineError<A, M, E>

fn clone(&self) -> MachineError<A, M, E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<A, M, E: Debug> Debug for MachineError<A, M, E>

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

Formats the value using the given formatter.

impl<A, M, E> Display for MachineError<A, M, E>

where E: Display,

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

Formats the value using the given formatter.

impl<A, M, E> Error for MachineError<A, M, E>

where E: Error + 'static, Self: Debug + Display,

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<A: PartialEq, M: PartialEq, E: PartialEq> PartialEq for MachineError<A, M, E>

fn eq(&self, other: &MachineError<A, M, E>) -> 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.
