From 1bde6e3fcb32ca00cf8a8dfa0977e47f7f4a77bf Mon Sep 17 00:00:00 2001 From: Aaron Turon Date: Thu, 5 Jun 2014 23:18:51 -0700 Subject: Rename Iterator::len to count This commit carries out the request from issue #14678: > The method `Iterator::len()` is surprising, as all the other uses of > `len()` do not consume the value. `len()` would make more sense to be > called `count()`, but that would collide with the current > `Iterator::count(|T| -> bool) -> unit` method. That method, however, is > a bit redundant, and can be easily replaced with > `iter.filter(|x| x < 5).count()`. > After this change, we could then define the `len()` method > on `iter::ExactSize`. Closes #14678.
