Compile error due to the wrong literal data type #68951
Description
I tried this code:
fn main() { let array = [0x42u8; 10]; for b in &array { let lo = b & 0xf; let hi = (b >> 4) & 0xf; } }I expected to see this happen: it should be compiled
Instead, this happened:
error[E0277]: no implementation for `u8 & i32` --> src/main.rs:5:27 | 5 | let hi = (b >> 4) & 0xf; | ^ no implementation for `u8 & i32` | = help: the trait `std::ops::BitAnd<i32>` is not implemented for `u8` Meta
