Currently it is not directly possible to configure lints for the entire workspace via TOML, which forced us to repeat `#![allow]` blocks in each crate. embark pointed out this workaround to configure lints at the workspace level via RUSTFLAGS: EmbarkStudios/rust-ecosystem#22 (comment) Remove the common `#![allow]` blocks and switch to this method for global lint config. Temporarily allow `needless_borrow` lint, buggy pending this fix: rust-lang/rust-clippy#8355

Does this also fix this case? pub fn put_u16(v: u16, out: &mut [u8]) {
let out: &mut [u8; 2] = (&mut out[..2]).try_into().unwrap();
*out = u16::to_be_bytes(v);
}Warning: --> rustls/src/msgs/codec.rs:91:29

91 | let out: &mut [u8; 2] = (&mut out[..2]).try_into().unwrap();
| ^^^^^^^^^^^^^^^ help: change this to: `out[..2]`

Oh no, another instance, where GitHub didn't show me a notification for a force push. @Jarcho please approve this PR yourself with |
`needless_borrow` will now walk further to find the target type.
Merge `Position` and `AutoDerefStability`

Though rust-lang/rust-clippy#8355 has been merged, it seems to still report false-positives on nightly channel. For now just fix the instances reported by stable clippy, and keep `needless_borrow` allowed.
