Add Extend::{extend_one,extend_reserve}

2020-05-30T00:05:17+00:00

This adds new optional methods on `Extend`: `extend_one` add a single element to the collection, and `extend_reserve` pre-allocates space for the predicted number of incoming elements. These are used in `Iterator` for `partition` and `unzip` as they shuffle elements one-at-a-time into their respective collections.

More diagnostic items for Clippy usage

2020-04-22T05:57:56+00:00

This adds a couple of more diagnostic items to be used in Clippy. I chose these particular ones because they were the types which we seem to check for the most in Clippy. I'm not sure if the `cfg_attr(not(test))` is needed, but it was also used for `Vec` and a few other types.

Optimize strip_prefix and strip_suffix with str patterns

2020-03-30T15:10:21+00:00

Constructing a Searcher in strip_prefix and strip_suffix is unnecessarily slow when the pattern is a fixed-length string. Add strip_prefix and strip_suffix methods to the Pattern trait, and add optimized implementations of these methods in the str implementation. The old implementation is retained as the default for these methods.

Implement From<&mut str> for String I ran into this missing impl when trying to do `String::from` on the result returned from this API in the `uuid` crate: https://docs.rs/uuid/0.8.1/uuid/adapter/struct.Hyphenated.html#method.encode_lower I wasn't sure what to put in the stability annotation. I'd appreciate some help with that :)
