Enum FlowError 

pub enum FlowError {
    InvalidTransition {
        from: TaskExecState,
        to: TaskExecState,
    },
    InvalidFlowTransition {
        from: FlowState,
        to: FlowState,
    },
    TaskNotFound(Uuid),
    TasksNotComplete,
}

Errors that can occur during flow operations.

Variants

InvalidTransition

Invalid task state transition.

Fields

from: TaskExecState

to: TaskExecState

InvalidFlowTransition

Invalid flow state transition.

Fields

from: FlowState

to: FlowState

TaskNotFound(Uuid)

Task not found.

TasksNotComplete

Cannot complete flow with incomplete tasks.

Trait Implementations

impl Clone for FlowError

fn clone(&self) -> FlowError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlowError

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

Formats the value using the given formatter.

impl Display for FlowError

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

Formats the value using the given formatter.

impl Error for FlowError

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 FlowError

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