Struct ActionMap 

pub struct ActionMap<A> { /* private fields */ }

Named action set, e.g. "gameplay" vs "menu". With no contexts every action is live; otherwise only actions in an active context fire.

Implementations

impl<A: Clone + Eq + Hash> ActionMap<A>

pub fn new() -> Self

pub fn bind(&mut self, action: A, binding: Binding) -> &mut Self

Bind one more physical source to an action.

pub fn in_context(&mut self, context: &str, action: A) -> &mut Self

Put an action in a named context.

pub fn bindings_for(&self, action: &A) -> &[Binding]

All bindings driving action (empty if unbound).

pub fn actions(&self) -> impl Iterator<Item = &A>

Actions holding at least one binding.

pub fn has_contexts(&self) -> bool

True when the map defines no contexts at all.

pub fn live_in(&self, action: &A, active: &HashSet<String>) -> bool

True when action may fire under active contexts. Actions in no context stay live (shared buttons like pause).

Trait Implementations

impl<A: Default> Default for ActionMap<A>

fn default() -> Self

Returns the “default value” for a type.
