Keeps the method consistent with `Iterator::any`. Closes rust-lang#22617 [breaking-change]
…iveness, but is necessary for now to work around rust-lang#22806. Fixes rust-lang#22655.
Changes .or() so that it can return a Result with a different E type
than the one it is called on.
Essentially:
fn or(self, res: Result<T, E>) -> Result<T, E>
becomes
fn or<F>(self, res: Result<T, F>) -> Result<T, F>
This brings `or` in line with the existing `and` and `or_else` member
types.
This is a
[breaking-change]
Due to some code needing additional type annotations.
which starts happening after ~2 hours of machine uptime.
The branch "else { continue }" is the last code inside a loop body,
it is just useless.

r? @steveklabnik Closes rust-lang#22698 I wasn't sure that this was appropriate for the book, but I've added this to the reference. I also noticed that one of the U+ symbols in the character literals section was missing the graves.
When warnings and errors occur, the associated help message should not print the same code snippet. rust-lang#21938
Check for unbounded recursion during dropck. Such recursion can be introduced by the erroneous use of non-regular types (aka types employing polymorphic recursion), which Rust does not support. Fix rust-lang#22443

…ecursion, r=pnkfelix Change MarkerTrait to be invariant. This is a (small) loss of expressiveness, but is necessary for now to work around rust-lang#22806. Fixes rust-lang#22655. r? @pnkfelix
