Can you add documentation saying that the last element returned, if any, contains the remainder of the data? Otherwise r=me |
This commit is an implementation of [RFC 979][rfc] which changes the meaning of the count parameter to the `splitn` function on strings and slices. The parameter now means the number of items that are returned from the iterator, not the number of splits that are made. [rfc]: rust-lang/rfcs#979 Closes rust-lang#23911 [breaking-change]

Uh. I wish this had also included a change that breaks at compile time, like renaming the function or something. As it is, it seems likely to cause silent breakage. |

Yep, this siliently bit me. Thankfully I had tests, but it was quite confusing. |

@SimonSapin @seanmonstar Yes, this was an unfortunate rush, and I apologize for the inconvenience. |
