Use byte string instead of slice of byte characters

[matthiasbeyer]

What it does

I accidentially used

let a = &[b'a', b'/', b'b'];

instead of

let a = b"a/b";

so I figured this could be a clippy lint.

Lint Name

bytestring_instead_of_byte_chars

Category

style

Advantage

• Easier to read
• Easier to change/extend

Drawbacks

None

Example

let a = &[b'a', b'/', b'b'];

Could be written as:

let a = b"a/b";

If this is wanted, I would like to try to contribute the implementation for it.

Sounds like a good lint to me, would be great if you'd like to implement it. If you have any questions ever you can ask here or on the Zulip channel
