Expand description
A no_std interface to the userspace Linux ABI designed to have no overhead, but still be safe
when possible by leveraging Rust’s type system.
§Result overhead
Although types like Result<(), i32> are sometimes used in place of the smaller i32 which
can both represent errors and values on success, it doesn’t add memory overhead or register
pressure in practice because functions are inlined.
To verify this, try to look at the assembler generated by this code when optimizations are enabled:
extern "C" {
fn fallible() -> i32;
fn test_succeeded();
fn test_failed(err: i32);
}
fn fallible_safe() -> Result<(), i32> {
let ret = unsafe { fallible() };
if ret < 0 {
return Err(ret);
}
Ok(())
}
pub fn test() {
if let Err(e) = fallible_safe() {
unsafe { test_failed(e) };
return;
}
unsafe { test_succeeded() };
