23-23: Dependency change fromahashtogxhashlooks good and is aligned with the PR's objectives.src/ngram.rs (2)
2-2: Switch toGxHashMapfromgxhashcrate is consistent with the project-wide changes.
6-7: The functionget_token_ngram_counternow usesGxHashMapfor ngram counting. Ensure that all usages of this function are compatible with the new return type.Verification successful
The function
get_token_ngram_counteris used insrc/bleu.rsand the operations on its return typeGxHashMap<&[String], usize>are compatible with the new return type. The code correctly handles the hashmap operations.
Scripts Executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Verify all function calls to `get_token_ngram_counter` handle the new return type correctly. # Test: Search for the function usage. Expect: Only occurrences of the new return type. rg --type rust $'get_token_ngram_counter'Length of output: 657
Script:
#!/bin/bash # Extract lines around the usage of `get_token_ngram_counter` in `src/bleu.rs` to verify handling of the new return type. rg -A 5 -B 5 'get_token_ngram_counter' src/bleu.rsLength of output: 948

64-64: Replacement ofAHashMapwithGxHashMapincompute_scorefunction aligns with the new hashing strategy. Ensure the performance characteristics meet the project's requirements.
