}Expand description
Export a patch module manifest with a stable C ABI.
This macro is intended for cdylib patch crates.
Example:
ⓘ
use hotpatch_rs::{hotpatch_module, PatchFn};
unsafe extern "C" fn handler(state: *mut core::ffi::c_void, input: *const core::ffi::c_void, output: *mut core::ffi::c_void) -> i32 {
0
}
hotpatch_module!("counter", 1, [("counter.add", handler)]);
