Description
b" hi".trim_ascii();
If it's not enabled it even suggests to enable the feature gate #![feature(byte_slice_trim_ascii)]
It would be nice to have a code action that adds it to the crate root.

Research direction
Start by tracing rust-analyzer's existing code-action handling for nightly feature-gate suggestions, using the b" hi".trim_ascii() example as the reproduction. The work is complete when a code action adds #![feature(byte_slice_trim_ascii)] to the crate root when the gate is missing.
