It looks like it triggers for size_of_val as well. I don't think it should do this.
#![warn(clippy::size_of_as_bits)]
use std::mem;
fn main() {
let x = 0u32;
println!("{}", 8 * mem::size_of_val(&x));
}
warning: you seem to be using `mem::size_of::<T>()` to obtain the size of `T` in bits

7 | println!("{}", 8 * mem::size_of_val(&x));
| ^^^^^^^^^^^^^^^^^^^^^^^^ help: consider using: `u32::BITS`

note: the lint level is defined here

1 | #![warn(clippy::size_of_as_bits)]
