#[repr(C)]pub struct Signature(_);
Expand description
A Signature specifies which receiver is valid for a function.
A receiver matches a given signature if the receiver (or any of its hidden prototypes) was created from the signature’s FunctionTemplate, or from a FunctionTemplate that inherits directly or indirectly from the signature’s FunctionTemplate.
