131-140: The logic for retrieving and processing list items from bindings has been refactored. Ensure that the new logic correctly handles all edge cases, especially with regards to list indexing and bounds checking.
164-173: Similar to the previous comment, the changes in the mutable version of the list item retrieval (get_mut) should be carefully reviewed to ensure that the logic for handling list indexes and bounds is correct and does not introduce any regressions.crates/core/src/pattern/contains.rs (1)
272-272: The simplification of handlingLazyBuiltIn::Joinby directly assigning a cloned list toResolvedPattern::Listis a positive change for code maintainability. Ensure that this change does not affect the expected behavior of theContainsmatcher, especially in edge cases.crates/core/src/pattern/built_in_functions.rs (2)
369-372: The refactoring in thejoin_fnfunction to handle list bindings more efficiently is a good improvement. However, ensure that the new logic correctly handles all types of bindings and does not introduce any unintended behavior.
482-486: The changes in thelength_fnfunction to improve length calculations are noteworthy. It's important to verify that the new logic for handling list items and calculating lengths is accurate and does not introduce any errors, especially in edge cases.crates/core/src/binding.rs (1)
534-534: The update to thelist_itemsfunction signature to return an iterator that implements theClonetrait is a positive change for enhancing usability and flexibility. Ensure that this change integrates well with existing usages of thelist_itemsfunction throughout the codebase.Verification successful
The update to the
list_itemsfunction signature to return an iterator that implements theClonetrait has been successfully integrated into the codebase. The explicit utilization of the cloning capability in various parts of the codebase confirms the enhancement in usability and flexibility. This change allows for more versatile handling of list items, as evidenced by the usage patterns found in the codebase.Scripts Executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Verify that the update to the `list_items` function signature integrates well with existing usages throughout the codebase.Length of output: 0
Script:
#!/bin/bash # Search for usages of the `list_items` function to verify integration with the updated signature. rg "list_items" --type rustLength of output: 2466
crates/core/src/pattern/resolved_pattern.rs (5)
103-103: TheJoinFnstruct now directly uses aVector<ResolvedPattern<'a>>for itslistfield, aligning with the refactor's goal to simplify list bindings by removing intermediary structures likeListBindingandListsenum. This change should make the handling of list items more straightforward and potentially improve performance by avoiding lazy retrieval patterns.
109-109: Thefrom_resolvedconstructor method forJoinFnis straightforward and correctly initializes theJoinFnstruct with the provided list and separator. This method aligns with the refactor's objectives by supporting the direct use ofVector<ResolvedPattern<'a>>.
112-116: Thefrom_list_bindingmethod has been adapted to work with the new structure ofJoinFn. However, it's important to note that this method still references the concept of a list binding through its parameter and internal logic. Given the refactor's goal to simplify list bindings, consider if there's a more direct way to achieve this functionality without indirectly referencing the removedListBindingstruct. This might involve reevaluating how list items are passed toJoinFninstances throughout the codebase.
128-143: Thelinearized_textmethod inJoinFncorrectly iterates over the list items, applying thelinearized_textmethod to each, and then joins them with the specified separator. This implementation is efficient and aligns with the refactor's objectives. However, ensure that thelinearized_textmethod ofResolvedPatternis optimized for this use case, especially considering the potential complexity of nested patterns.
147-153: Thetextmethod inJoinFnis similar tolinearized_textbut for generating a simpler text representation. It's correctly implemented and follows the same pattern of iterating over list items, applying thetextmethod, and joining with the separator. This method is essential for scenarios where a more straightforward text representation is needed, and it aligns well with the refactor's goals.

Is this what you referring to where you had to eagerly evaluate? I think this is fine. The purpose of the function structs is to be able to lazily evaluate the text the nodes are pointing to. Specifically if a function is on the right hand side of a rewrite then the function will be evaluated at linearization time. Sometimes the functions are eagerly evaluated eg. the text function eagerly evaluates the enclosed resolved pattern.

Thanks! This is the one indeed.
This PR simplifies list bindings by getting of the
Listsenum and theListBindingstruct, both inresolved_pattern.rs.This involves a compromise: Instead of lazily retrieving the list items, this eagerly retrieves them when creating the
JoinFn. The tests seem fine with this, but let me know if this has other repercussions.Summary by CodeRabbit
