programmatically invoking a break point

Question

In rust is there any way to break into the debugger. C# has DebugBreak which when executed simply behaves the same way as though a break point was set there.

Breaking on panic I know how to do and thats not what I am looking for.

Answer 1

Yes, there's ::std::intrinsics::breakpoint (unstable/feature-gated, so only available on nightly Rust):

#![feature(core_intrinsics)]

use ::std::intrinsics::breakpoint;

fn main() {
    unsafe { breakpoint() };
}
