rustc: Remove `&str` indexing from the language. Being able to index into the bytes of a string encourages poor UTF-8 hygiene. To get a view of `&[u8]` from either a `String` or `&str` slice, use the `as_bytes()` method. Closes #12710. [breaking-change] 2014-06-20 01:22:33 +00:00			`let s: &str = "hello";`
Make `str` indexing generic on `SliceIndex`. 2019-01-14 13:10:45 +00:00			let _: u8 = s[4]; //~ ERROR the type `str` cannot be indexed by `{integer}`
			let _ = s.get(4); //~ ERROR the type `str` cannot be indexed by `{integer}`
			let _ = s.get_unchecked(4); //~ ERROR the type `str` cannot be indexed by `{integer}`
			let _: u8 = s['c']; //~ ERROR the type `str` cannot be indexed by `char`
Reformat This changes the indexing syntax from .() to [], the vector syntax from ~[] to [] and the extension syntax from #fmt() to #fmt[] 2011-08-19 22:16:48 +00:00			`}`
