Expand description
Static assert (i.e. compile-time assert).
Similar to C11 _Static_assert
and C++11 static_assert
.
The feature may be added to Rust in the future: see RFC 2790.
§Examples
static_assert!(42 > 24);
static_assert!(core::mem::size_of::<u8>() == 1);
const X: &[u8] = b"bar";
static_assert!(X[1] == b'a');
const fn f(x: i32) -> i32 {
x + 2
}
static_assert!(f(40) == 42);
