An intrinsic was declared without being a function.
Erroneous code example:
#![feature(intrinsics)]
extern "rust-intrinsic" {
pub static breakpoint : fn(); // error: intrinsic must be a function
}
fn main() { unsafe { breakpoint(); } }An intrinsic is a function available for use in a given programming language whose implementation is handled specially by the compiler. In order to fix this error, just declare a function. Example:
#![feature(intrinsics)]
extern "rust-intrinsic" {
pub fn breakpoint(); // ok!
}
fn main() { unsafe { breakpoint(); } }
