Struct v8::Signature

source ·
#[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.
