Functions ¶

func CloseBadgerDB ¶

func CloseBadgerDB(db *badger.DB)

func ComputeFileHash ¶

func ComputeFileHash(filePath string, useFastHash bool) (string, error)

ComputeFileHash calculates a hash for the file. If useFastHash is true and the file is larger than FastHashThreshold, it computes a partial hash based on the beginning, middle, and end of the file. Otherwise, it computes the full MD5.

func ExtractHeicExif ¶

func ExtractHeicExif(r io.ReaderAt) ([]byte, error)

ExtractHeicExif parses a HEIC file (ISOBMFF) and extracts the raw EXIF data block.

func GetBadgerDBValue ¶

func GetBadgerDBValue(db *badger.DB, hashKey string) (string, error)

func IterateWithPrefix ¶

func IterateWithPrefix(db *badger.DB, prefix string) ([]string, error)

func Md5Sum ¶

func Md5Sum(filePath string) (string, error)

Md5Sum returns the MD5 checksum of the file at the given path.

func OpenBadgerDB ¶

func OpenBadgerDB(path string) (*badger.DB, error)

func PutBadgerDB ¶

func PutBadgerDB(db *badger.DB, hashKey string, fileNameValue string) error

func ReadJpegDate ¶

func ReadJpegDate(ctx context.Context, db *badger.DB, src_dirname string, options ScanOptions) ([]FileObject, []ErroredFileObject)

func ReadVideoCreationTimeMetadata ¶

func ReadVideoCreationTimeMetadata(ctx context.Context, db *badger.DB, src_dirname string, options ScanOptions) ([]FileObject, []ErroredFileObject)

func ScanAndGenerateMd5sumFiles ¶

func ScanAndGenerateMd5sumFiles(ctx context.Context, db *badger.DB, dirname string, prefix string, options ScanOptions)

func ScanFiles ¶

func ScanFiles(ctx context.Context, src_dirname string, dst_dirname string, options ScanOptions)

func SortFilesByDate ¶

func SortFilesByDate(files []FileObject)
