Instance Method Summary

• #bind(emitter_id : UInt64, signal_name : String, callback : Proc(*T, R), once : Bool = false) : UInt64 forall T, R

  Binds a compile-time typed Proc(*T, R) to (emitter_id, signal_name).

• #bind(emitter : Godot::Object, signal_name : String, callback : Proc(*T, R), once : Bool = false) : UInt64 forall T, R

  Binds a compile-time typed Proc(*T, R) to (emitter, signal_name).

• #bind_by_hash(emitter_id : UInt64, signal_hash : UInt64, callback : Proc(*T, R), once : Bool = false) : UInt64 forall T, R

  Binds a compile-time typed Proc(*T, R) to (emitter_id, signal_hash).

• #clear_emitter(emitter_id : UInt64) : Int32

  Clears all signal bindings for emitter_id.

• #clear_emitter(emitter : Godot::Object) : Int32

  Clears all signal bindings for emitter.

• #emit(emitter_id : UInt64, signal_name : String, *args : *T) : Int32 forall T

  Emits (emitter_id, signal_name) with *args with strictly zero GC heap allocations.

• #emit(emitter : Godot::Object, signal_name : String, *args : *T) : Int32 forall T

  Emits (emitter, signal_name) with *args with strictly zero GC heap allocations.

• #slot(emitter_id : UInt64, signal_name : String, *types : *T) forall T

  Returns a typed StaticSignalSlot(*T) bound to (emitter_id, signal_name).

• #slot(emitter : Godot::Object, signal_name : String | Symbol, *types : *T) forall T

  Returns a typed StaticSignalSlot(*T) bound to (emitter, signal_name).

• #table : Lapis::Core::StaticSignalTable
• #unbind(emitter_id : UInt64, signal_name : String, callback : Proc(*T, R)) : Bool forall T, R

  Unbinds a matching Proc(*T, R) from (emitter_id, signal_name).

• #unbind(emitter : Godot::Object, signal_name : String, callback : Proc(*T, R)) : Bool forall T, R

  Unbinds a matching Proc(*T, R) from (emitter, signal_name).

• #unbind(token : UInt64) : Bool

  Unbinds a listener slot by token.
