func FindTestRegion ¶ added in v0.22.0

func FindTestRegion(content []byte) (startLine, endLine int, ok bool)

FindTestRegion returns the inclusive 1-indexed line range covering test-only code in a Rust source file. A test region is any item carrying an attribute that gates it to test builds:

• `#[cfg(test)]`, `#[cfg(all(test, ...))]`, `#[cfg(any(test, ...))]` (and nested combinations), but NOT `#[cfg(not(test))]`
• `#[test]`, `#[tokio::test]`, `#[async_std::test]`, `#[rstest]`, `#[test_case]`

Doctests inside `///` comments are NOT counted. Returns ok=false when no such region exists.

Known limitation: the item-end finder uses naive brace counting and does not strip string literals or `// }` comments. Hand-crafted Rust that places a `}` inside a string in the test region can mis-balance the count.

func IsTestFile ¶

func IsTestFile(filePath string) bool

IsTestFile reports whether the given Rust path is a test file.

func IsTestFileWithContent ¶

func IsTestFileWithContent(filePath string, contentReader vcs.ContentReader) bool

IsTestFileWithContent reports whether the given Rust path is a test file, using file content when available to confirm.

func ResolveRustProjectImports ¶

func ResolveRustProjectImports(
	absPath string,
	filePath string,
	suppliedFiles map[string]bool,
	contentReader vcs.ContentReader,
) ([]string, error)

func SplitDiff ¶ added in v0.22.0

func SplitDiff(oldContent, newContent []byte, diff vcs.FileDiff) (prod, test vcs.FileStats)

SplitDiff attributes per-line additions and deletions to prod vs test using the test region found in oldContent (for deletions) and newContent (for additions). Either content may be nil/empty: oldContent is empty for new files; newContent is empty for deletions.
