Enum ActionError 

pub enum ActionError {
    NoPendingDecision,
    InvalidActionId {
        action_id: usize,
    },
    ActionNotLegal,
}

Stable error categories for action application.

Variants

NoPendingDecision

An action was attempted when no decision is pending.

InvalidActionId

An action id could not be decoded or is outside the action space.

Fields

action_id: usize

Provided action id.

ActionNotLegal

An action id was decoded but is not legal for the current decision.

Trait Implementations

impl Clone for ActionError

fn clone(&self) -> ActionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActionError

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

Formats the value using the given formatter.

impl Display for ActionError

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

Formats the value using the given formatter.

impl Error for ActionError

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 ActionError

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