Expand description
Represents a custom callable object defined in Rust.
This trait has a single method, invoke
, which is called upon invocation.
Since callables can be invoked from anywhere, they must be self-contained ('static
) and thread-safe (Send + Sync
).
They also should implement Display
for the Godot string representation.
Furthermore, PartialEq
and Hash
are required for equality checks and usage as a key in a Dictionary
.

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.
