… C++'s std::nth_element (a.k.a. quickselect) Add some more notes to the documentation: - Mention that the median can be found if we used `len() / 2`. - Mention that this function is usually called "kth element" in other libraries. Address some comments in PR: - Change wording on some of the documentation - Change recursive function into a loop Update name to `partition_at_index` and add convenience return values. Address reviewer comments: - Don't swap on each iteration when searching for min/max element. - Add some docs about when we panic. - Test that the sum of the lengths of the output matches the length of the input. - Style fix for for-loop. Address more reviewer comments Fix Rng stuff for test Fix doc test build Don't run the partition_at_index test on wasm targets Miri does not support entropy for test partition_at_index
The `InlineAsm` variant is extremely rare, and `mir::Statement` often contributes significantly to peak memory usage.
Add 'partition_at_index/_by/_by_key' for slices. This is an analog to C++'s std::nth_element (a.k.a. quickselect). Corresponds to tracking bug rust-lang#55300.
…ited_again, r=KodrAus improve worst-case performance of BTreeSet intersection v3 Variation of [rust-lang#59078](rust-lang#59078) with `Intersection` remaining a struct r? @scottmcm
…ion-elem, r=eddyb Remove adt_def from projections and downcasts in MIR As part of optimizing generator layouts in MIR, we'd like to allow downcasting generators to variants which do not have a corresponding `def_id`, since they are created by the compiler. This refactor hopes to allow that, without regressing perf. r? @eddyb
…=pnkfelix Shrink `mir::Statement`. The `InlineAsm` variant is extremely rare, and `mir::Statement` often contributes significantly to peak memory usage.
