Struct GuardError 

pub struct GuardError {
    pub guard: &'static str,
    pub event: &'static str,
    pub kind: TransitionErrorKind,
}

Error returned when a guard or around callback fails in typestate mode.

In typestate machines, guards and around callbacks can fail even though the transition is valid. The machine is returned along with this error so the caller can retry or handle it.

Fields

guard: &'static str

event: &'static str

kind: TransitionErrorKind

Implementations

impl GuardError

pub const fn new(guard: &'static str, event: &'static str) -> Self

pub const fn with_kind( guard: &'static str, event: &'static str, kind: TransitionErrorKind, ) -> Self

Trait Implementations

impl Clone for GuardError

fn clone(&self) -> GuardError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GuardError

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

Formats the value using the given formatter.

impl PartialEq for GuardError

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