#[repr(C)]
pub struct SignalInner { /* private fields */ }
Expand description

Internal class that can be used to construct C++ signal. Should only be used as an implementation details when writing bindings to Qt signals to construct a Signal<...>.

It has the same size as any pointer to a member function like void (QObject::*)(), and can be constructed from signals defined in both C++ classes and Rust structs.

To learn more about internals, take a look at documentation in qmetaobject_rust.hpp source file.

Implementations§

source§

impl SignalInner

source

pub fn from_offset<O: QObject + Sized>(offset: isize) -> Self

Construct signal representation from offset of the signal relative to the base address of the object.

Panics

Tl; dr: signal struct self must belong to the object obj.

This method panics if the signal offset lies outside of object’s memory space, i.e. if the offset is less than 0 or greater or equal to object’s size. Object’s size must be known at compile time.
