Summary of Changes
Hello @satler-git, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
I've implemented a new feature that provides more flexibility in how sorters are applied. This change introduces a mechanism to reverse the order in which multiple sorters are processed, allowing for different sorting behaviors without altering the individual sorter definitions. This enhances the configurability of the batching and sorting logic.
Highlights
- New Sorting Order Control: I've introduced a new
reversed_sorter_apply_orderflag within theBatcherstruct. This flag controls whether the defined sorters are applied in their original sequence or in reverse order, offering more control over the sorting process. - Public API for Launcher: To expose this new functionality, I've added a public method
reversed_sorter_apply_orderto theLauncherstruct. This allows external users to easily configure the sorter application order. - Dynamic Sorter Application: The internal
create_sorterfunction inBatcherhas been updated to dynamically iterate through the sorters. It now uses a newcompare!macro and conditional loops to apply sorters either forwards or in reverse, depending on thereversed_sorter_apply_orderflag.

Code Review
This pull request introduces a feature to reverse the application order of sorters. The implementation is sound, but I have a couple of suggestions to improve maintainability. I've recommended adding documentation for the new public API and refactoring the sorting logic to be more idiomatic and readable by removing a macro and duplicated code.

src/launcher/batcher.rs (3)
31-31: Document the new flag and clarify its semanticsPlease add a short doc comment clarifying that this flag reverses the order of applying sorters (i.e., last → first), which changes tie-breaker priority, and that the default is false. This helps distinguish it from
reverse_sorter, which flips the final ordering direction without changing priority.Example:
pub struct Batcher<'a, Cushion, UIContext> { @@ - pub(super) reversed_sorter_apply_order: bool, + /// If true, apply sorters in reverse declaration order (last → first) when comparing. + /// This changes the tie-breaker priority among sorters. Default is false. + pub(super) reversed_sorter_apply_order: bool, @@ - reversed_sorter_apply_order: false, + // Apply sorters in forward order by default (first → last). + reversed_sorter_apply_order: false,Also applies to: 50-50
142-142: Local import is fine; optional: avoid shadow imports for clarityUsing
use std::cmp::Ordering;inside the closure is valid, but in practice pulling the type at module scope or qualifying (e.g.,std::cmp::Ordering::Equal) can improve readability and reduce repetition across closures.
147-163: Comparator macro is correct; consider inlining for readabilityThe macro correctly short-circuits and uses
continuewithin the loops. If you prefer to avoid macros here, you can inline the body once per loop using a tiny helper closure to compute the finalOrdering, keeping the logic local and explicit.For example:
- macro_rules! compare { - ($i:ident) => { - match self.sorters[$i].compare(lhs, rhs, &self.state.input) { - Ordering::Equal => { - continue; - } - ord => { - return if self.reverse_sorter { - ord.reverse() - } else { - ord - }; - } - } - }; - } + let mut finalize = |ord: Ordering| { + if self.reverse_sorter { ord.reverse() } else { ord } + };And use the body directly in each loop:
let ord = self.sorters[i].compare(lhs, rhs, &self.state.input); if ord != Ordering::Equal { return finalize(ord); }This keeps the flow explicit with minimal duplication.

185-188: Add docs for the new API and align naming withreverse_sorterThe method is correctly wired to
Batcher. Please add a brief doc comment clarifying that this toggles the order of applying sorters (affecting tie-breaker priority), distinct fromreverse_sorterwhich flips the final ordering direction.Optionally, consider a slightly clearer name like
apply_sorters_in_reversefor readability; current name is accurate but a bit heavy.Example:
- pub fn reversed_sorter_apply_order(mut self, flag: bool) -> Self { + /// If true, apply sorters in reverse declaration order (last → first) when comparing. + /// This changes tie-breaker priority among sorters. Default is false. + pub fn reversed_sorter_apply_order(mut self, flag: bool) -> Self { self.batcher.reversed_sorter_apply_order = flag; self }
