**/*.rs
📄 CodeRabbit Inference Engine (AGENTS.md)
**/*.rs: Run cargo fmt, cargo clippy -- -D warnings, and RUSTFLAGS="-D warnings" cargo test before committing.
Clippy warnings MUST be disallowed.
Fix any warnings emitted during tests in the code itself rather than silencing them.
Where a function is too long, extract meaningfully named helper functions adhering to separation of concerns and CQRS.
Where a function has too many parameters, group related parameters in meaningfully named structs.
Where a function is returning a large error consider using Arc to reduce the amount of data returned.
Write unit and behavioural tests for new functionality. Run both before and after making any change.
Document public APIs using Rustdoc comments (///) so documentation can be generated with cargo doc.
Prefer immutable data and avoid unnecessary mut bindings.
Handle errors with the Result type instead of panicking where feasible.
Avoid unsafe code unless absolutely necessary and document any usage clearly.

src/cli_args.rs (1)
26-26: Excellent idiomatic improvement usingSelf.This change satisfies the
use_selfclippy lint and improves code consistency.Cargo.toml (1)
24-25: Good addition of optional parsing dependencies.The explicit
dep:syntax in the feature definitions is correct modern Cargo practice.docs/vk-design.md (1)
70-74: Excellent documentation of new configuration features.The new section clearly explains the optional JSON5 and YAML support and aligns perfectly with the Cargo.toml changes.
src/main.rs (13)
58-60: Excellent use ofSelf::for enum variants.This satisfies the
use_selfclippy lint and improves code consistency.
91-93: Good improvement using.expect()with descriptive messages.Replacing
.unwrap()with.expect("valid regex")provides better error diagnostics when regex compilation fails.Also applies to: 95-96, 101-101
219-222: Well-documented lint suppressions with explicit reasons.The expanded
#[allow]attributes with reasons satisfy the coding guidelines requirement to avoid blanket suppressions.Also applies to: 242-242
454-454: Appropriate use of.to_owned()for string cloning.This is more semantically correct than
.to_string()when cloning existing strings.Also applies to: 459-459
480-482: Good replacement of string slicing with.split_off().This avoids potential panics from string slicing and is more explicit about the intent.
491-513: Excellent refactor usingmap_or_elsefor cleaner control flow.The replacement of if-else logic with
map_or_elseis more idiomatic and improves readability.
518-521: Outstanding use of safe indexing with.get()and fallbacks.Replacing direct indexing with
.get()and.unwrap_or(&[])prevents potential panics and satisfies theindexing_slicing = "deny"lint requirement.Also applies to: 524-524
638-650: Good use of.expect()for static string parsing.Using
.expect("static string")and.expect("valid header")provides better error context than.unwrap().
654-657: Proper lint suppression with detailed reasoning.The
#[allow(clippy::result_large_err)]attributes with explanatory reasons follow the coding guidelines for narrow, documented lint suppressions.Also applies to: 688-691, 740-743, 760-763, 806-809, 817-820
774-790: Excellent replacement of unsafe indexing with bounds-checked access.Using
.get()with.expect("length checked")and.to_owned()instead of direct indexing and.to_string()improves both safety and semantic correctness.
830-832: Good use of.to_owned()for string extraction from regex captures.This is more semantically appropriate than
.to_string()when extracting owned strings from borrowed data.Also applies to: 841-854
845-847: Excellent use of iterator methods instead of collecting.Using
splitn(2, '/')with iterator methods instead of collecting into vectors is more efficient and clearer.
888-889: Consistent improvement using.expect()with descriptive messages.Throughout the test code, replacing
.unwrap()with.expect()provides better error diagnostics and aligns with the coding guidelines.Also applies to: 897-898, 906-906, 908-908, 913-918, 924-924, 931-931, 958-958, 961-961, 967-967, 988-991, 997-997, 1005-1005, 1009-1009, 1027-1027, 1036-1036, 1047-1047, 1058-1058, 1067-1067, 1076-1077, 1086-1087, 1095-1095, 1103-1103, 1155-1156, 1166-1166, 1192-1193
