Struct SigFramePostDraw

pub struct SigFramePostDraw<'c, C>
where
    C: WithSignals,
{ /* private fields */ }

Implementations

impl<'c, C> SigFramePostDraw<'c, C>

where C: WithSignals,

pub fn emit(&mut self)

Methods from Deref<Target = TypedSignal<'c, C, ()>>

pub fn builder<'ts>(&'ts self) -> ConnectBuilder<'ts, 'c, C, Ps>

Fully customizable connection setup.

The returned builder provides several methods to configure how to connect the signal. It needs to be finalized with a call to any of the builder’s connect_* methods.

pub fn emit_tuple(&mut self, args: Ps)

where Ps: OutParamTuple,

Emit the signal with the given parameters.

This is intended for generic use. Typically, you’ll want to use the more specific emit() method of the code-generated signal type, which also has named parameters.

pub fn connect<F>(&self, function: F) -> ConnectHandle

where F: for<'c_rcv> SignalReceiver<(), Ps> + 'static, IndirectSignalReceiver<'c_rcv, (), Ps, F>: for<'c_rcv> From<&'c_rcv mut F>,

Connect a non-member function (global function, associated function or closure).

Example usages:

sig.connect(Self::static_func);
sig.connect(global_func);
sig.connect(|arg| { /* closure */ });

• To connect to a method on the object that owns this signal, use connect_self().
• If you need connect flags or cross-thread signals, use builder().

pub fn connect_self<F, Declarer>(&self, function: F) -> ConnectHandle

where F: for<'c_rcv> SignalReceiver<&'c_rcv mut C, Ps> + 'static, IndirectSignalReceiver<'c_rcv, &'c_rcv mut C, Ps, F>: for<'c_rcv> From<&'c_rcv mut F>, C: UniformObjectDeref<Declarer>,

Connect a method (member function) with &mut self as the first parameter.

• To connect to methods on other objects, use connect_other().
• If you need connect flags or cross-thread signals, use builder().

pub fn connect_other<F, OtherC, Declarer>( &self, object: &impl ToSignalObj<OtherC>, method: F, ) -> ConnectHandle

where OtherC: UniformObjectDeref<Declarer>, F: for<'c_rcv> SignalReceiver<&'c_rcv mut OtherC, Ps> + 'static, IndirectSignalReceiver<'c_rcv, &'c_rcv mut OtherC, Ps, F>: for<'c_rcv> From<&'c_rcv mut F>,

Connect a method (member function) with any &mut OtherC as the first parameter, where OtherC: GodotClass (both user and engine classes are accepted).

The parameter object can be of 2 different “categories”:

• Any &Gd<OtherC> (e.g.: &Gd<Node>, &Gd<CustomUserClass>).
• &OtherC, as long as OtherC is a user class that contains a base field (it implements the WithBaseField trait).

• To connect to methods on the object that owns this signal, use connect_self().
• If you need connect flags or cross-thread signals, use builder().

pub fn to_fallible_future(&self) -> FallibleSignalFuture<R>

Creates a fallible future for this signal.

The future will resolve the next time the signal is emitted. See FallibleSignalFuture for details.

pub fn to_future(&self) -> SignalFuture<R>

Creates a future for this signal.

The future will resolve the next time the signal is emitted, but might panic if the signal object is freed. See SignalFuture for details.
