Enum RingActionError 

pub enum RingActionError {
    EmptyAction,
    RecursiveTrigger,
}

Why an Action cannot be placed in an Actions Ring slot.

Variants

EmptyAction

Empty slots are represented by an absent map entry, not Action::None.

RecursiveTrigger

A ring cannot recursively open itself.

impl Eq for RingActionError

impl Error for RingActionError

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
