Types

type FileDetector 

type FileDetector struct{}

FileDetector implements exact file duplicate detection.

func NewFileDetector 

func NewFileDetector() *FileDetector

NewFileDetector creates a new file-level hash detector.

func (*FileDetector) FindDuplOver 

func (f *FileDetector) FindDuplOver(ctx context.Context, data []*syntax.Node, threshold int) <-chan syntax.Match

FindDuplOver finds exact file duplicates using XXH3 hashing.

type FileDuplicate 

type FileDuplicate struct {
	Hash  string
	Files []FileHash
}

FileDuplicate represents a group of files with identical content.

func FindFileDuplicates 

func FindFileDuplicates(ctx context.Context, files []string, threshold int) []FileDuplicate

FindFileDuplicates finds exact file duplicates by hashing file contents. Files are hashed one at a time via io.Copy through XXH3 — file content is never held in memory. Only (hash, filename, size) is retained per file.

type FileHash 

type FileHash struct {
	Hash     string
	Filename string
	Size     int
}

FileHash represents a hash of a complete file.
