Trait callable 

pub trait callable {
    // Provided method
    fn __call(&self, args: Repeatable<any>) -> Repeatable<any> { ... }
}

Metamethod making a value callable.

Provided Methods

fn __call(&self, args: Repeatable<any>) -> Repeatable<any>

The call operation f(args). Invoked when Lua tries to call a non-function value: its __call metavalue is called with the value itself as the first argument, followed by the original arguments.

Examples

local counter = setmetatable({ n = 0 }, {
  __call = function(self)
    self.n = self.n + 1
    return self.n
  end,
})
print(counter(), counter(), counter())    --> 1   2   3

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
