An invalid number of generic parameters was passed to an intrinsic function.
Erroneous code example:
#![feature(intrinsics)]
extern "rust-intrinsic" {
fn size_of<T, U>() -> usize; // error: intrinsic has wrong number
// of type parameters
}Please check that you provided the right number of type parameters and verify with the function declaration in the Rust source code. Example:
#![feature(intrinsics)]
extern "rust-intrinsic" {
fn size_of<T>() -> usize; // ok!
}
