core::intrinsics::return_address

pub unsafe extern "rust-intrinsic" fn return_address() -> *const u8

Unstable (core_intrinsics #0)

: intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

[−] Expand description

Gives the address for the return value of the enclosing function.

Using this intrinsic in a function that does not use an out pointer will trigger a compiler error.
