Enum InputLifecycleError 

#[non_exhaustive]
pub enum InputLifecycleError {
    InvalidTransition {
        from: InputLifecycleState,
        input: String,
    },
    TerminalState {
        state: InputLifecycleState,
    },
    GuardFailed {
        from: InputLifecycleState,
        guard: String,
    },
}

Errors from the input lifecycle authority.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidTransition

The transition is not valid from the current state.

Fields

from: InputLifecycleState

input: String

TerminalState

The input is already in a terminal state.

Fields

state: InputLifecycleState

GuardFailed

A guard condition was not met.

Fields

from: InputLifecycleState

guard: String

Trait Implementations

impl Clone for InputLifecycleError

fn clone(&self) -> InputLifecycleError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InputLifecycleError

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

Formats the value using the given formatter.

impl Display for InputLifecycleError

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

Formats the value using the given formatter.

impl Error for InputLifecycleError

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.
