Provided Methods

fn add_action(&self, action: &impl IsA<Action>)

Adds an action to the @self.

If the action map already contains an action with the same name as @action then the old action is dropped from the action map.

The action map takes its own reference on @action.

action

a Action

fn lookup_action(&self, action_name: &str) -> Option<Action>

Looks up the action with the name @action_name in @self.

If no such action exists, returns NULL.

action_name

the name of an action

Returns

a Action

fn remove_action(&self, action_name: &str)

Removes the named action from the action map.

If no action of this name is in the map then nothing happens.

action_name

the name of the action

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
