The unifying theme for this commit is weak, admittedly. I put together a list of "expensive" functions when I originally proposed this whole effort, but nobody's cared about that criterion. Still, it's a decent way to bite off a not-too-big chunk of work. Given the grab bag nature of this commit, the messages I used vary quite a bit.

…ations, r=joshtriplett Add #[must_use] to expensive computations The unifying theme for this commit is weak, admittedly. I put together a list of "expensive" functions when I originally proposed this whole effort, but nobody's cared about that criterion. Still, it's a decent way to bite off a not-too-big chunk of work. Given the grab bag nature of this commit, the messages I used vary quite a bit. I'm open to wording changes. For some reason clippy flagged four `BTreeSet` methods but didn't say boo about equivalent ones on `HashSet`. I stared at them for a while but I can't figure out the difference so I added the `HashSet` ones in. ```rust // Flagged by clippy. alloc::collections::btree_set::BTreeSet<T> fn difference<'a>(&'a self, other: &'a BTreeSet<T>) -> Difference<'a, T>; alloc::collections::btree_set::BTreeSet<T> fn symmetric_difference<'a>(&'a self, other: &'a BTreeSet<T>) -> SymmetricDifference<'a, T> alloc::collections::btree_set::BTreeSet<T> fn intersection<'a>(&'a self, other: &'a BTreeSet<T>) -> Intersection<'a, T>; alloc::collections::btree_set::BTreeSet<T> fn union<'a>(&'a self, other: &'a BTreeSet<T>) -> Union<'a, T>; // Ignored by clippy, but not by me. std::collections::HashSet<T, S> fn difference<'a>(&'a self, other: &'a HashSet<T, S>) -> Difference<'a, T, S>; std::collections::HashSet<T, S> fn symmetric_difference<'a>(&'a self, other: &'a HashSet<T, S>) -> SymmetricDifference<'a, T, S> std::collections::HashSet<T, S> fn intersection<'a>(&'a self, other: &'a HashSet<T, S>) -> Intersection<'a, T, S>; std::collections::HashSet<T, S> fn union<'a>(&'a self, other: &'a HashSet<T, S>) -> Union<'a, T, S>; ``` Parent issue: rust-lang#89692 r? ``@joshtriplett``
…s, r=joshtriplett Add #[must_use] to mem/ptr functions There's a lot of low-level / unsafe stuff here. Are there legit use cases for ignoring any of these return values? * No regressions in `./x.py test --stage 1 library/std src/tools/clippy`. * One regression in `./x.py test --stage 1 src/test/ui`. Fixed. * I am unable to run `./x.py doc` on my machine so I'll need to wait for the CI to verify doctests pass. I eyeballed all the adjacent tests and they all look okay. Parent issue: rust-lang#89692 r? ``@joshtriplett``
…lett Add #[must_use] to remaining core functions I've run out of compelling reasons to group functions together across crates so I'm just going to go module-by-module. This is everything remaining from the `core` crate. Ignored by clippy for reasons unknown: ```rust core::alloc::Layout unsafe fn for_value_raw<T: ?Sized>(t: *const T) -> Self; core::any const fn type_name_of_val<T: ?Sized>(_val: &T) -> &'static str; ``` Ignored by clippy because of `mut`: ```rust str fn split_at_mut(&mut self, mid: usize) -> (&mut str, &mut str); ``` <del> Ignored by clippy presumably because a caller might want `f` called for side effects. That seems like a bad usage of `map` to me. ```rust core::cell::Ref<'b, T> fn map<U: ?Sized, F>(orig: Ref<'b, T>, f: F) -> Ref<'b, T>; core::cell::Ref<'b, T> fn map_split<U: ?Sized, V: ?Sized, F>(orig: Ref<'b, T>, f: F) -> (Ref<'b, U>, Ref<'b, V>); ``` </del> Parent issue: rust-lang#89692 r? ``@joshtriplett``
