I'd like to override only one of functions defined in another file or library.
The function is defined as pub extern "C" and it gives an error like this;
warning: Linking globals named 'left': symbol multiply defined!
error: failed to load bc of "example.j8aksdoc-cgu.1":
error: aborting due to previous error; 1 warning emitted
error: could not compile `example`
Is there anyway to override the pub extern function in rust?
[info/lib.rs]
#[no_mangle]
pub extern "C" fn left() {
return 10; // return constant value for easy test
}
[main.rs]
extern crate info;
pub extern "C" fn left() {
return 7; // need to override left function
}
