Overview

Implement split_inclusive for slice and str and split_inclusive_mut for slice
split_inclusive is a substring/subslice splitting iterator that includes the matched part in the iterated substrings as a terminator.
EDIT: The behaviour has now changed, as per @KodrAus 's input, to the same semantics with the split_terminator function. I updated the examples below.
Two examples below:

let data = "\nMäry häd ä little lämb\nLittle lämb\n";let split:Vec<&str> = data.split_inclusive('\n').collect();assert_eq!(split,["\n","Märy häd ä little lämb\n","Little lämb\n"]);

let uppercase_separated = "SheePSharKTurtlECaT";letmut first_char = true;let split:Vec<&str> = uppercase_separated.split_inclusive(|c:char| {let split = !first_char && c.is_uppercase();
first_char = split;
split
}).collect();assert_eq!(split,["SheeP","SharK","TurtlE","CaT"]);

Justification for the API

I was surprised to find that stdlib currently only has splitting iterators that leave out the matched part. In my experience, wanting to leave a substring terminator as a part of the substring is a pretty common usecase.
This API is strictly more expressive than the standard split API: it's easy to get the behaviour of split by mapping a subslicing operation that drops the terminator. On the other hand it's impossible to derive this behaviour from split without using hacky and brittle unsafe code. The normal way to achieve this functionality would be implementing the iterator yourself.
Especially when dealing with mutable slices, the only way currently is to use split_at_mut. This API provides an ergonomic alternative that plays to the strengths of the iterating capabilities of Rust. (Using split_at_mut iteratively used to be a real pain before NLL, fortunately the situation is a bit better now.)

Discussion items

Does it make sense to mimic split_terminator in that the final empty slice would be left off in case of the string/slice ending with a terminator? It might do, as this use case is naturally geared towards considering the matching part as a terminator instead of a separator.
- EDIT: The behaviour was changed to mimic split_terminator.
Does it make sense to have split_inclusive_mut for &mut str?

Hi @Centril. If you’d like help specifically from me feel free to mention me. If you believe highfive’s choice of reviewer is not appropriate (maybe that person is away for a couple weeks?) and need to find another reviewer please consider picking from https://github.com/rust-lang/highfive/blob/master/highfive/configs/rust-lang/rust.json.

(Why reassign a third time so soon after the second one?)

Ah didn't see that you reassigned.

Does it make sense to mimic split_terminator in that the final empty slice would be left off in case of the string/slice ending with a terminator?

I think this makes sense too, and is how I’d expect this to work.
