Nom-Exif
Exif/metadata parsing library written in pure Rust with nom.
Supported File Types
- Images
- JPEG
- HEIF/HEIC
- Videos
- MOV
- MP4
Features
- Zero-copy when appropriate: Use borrowing and slicing instead of copying whenever possible.
- Minimize I/O operations: When metadata is stored at the end/middle of a
large file (such as a MOV/HEIC file does),
Seek
rather thanRead
to quickly locate the location of the metadata. - Pay as you go: When extracting Exif data, only the information corresponding to the specified Exif tags are parsed to reduce the overhead when processing a large number of files.
- Robustness and stability: Through long-term Fuzz testing, and tons of crash issues discovered during testing have been fixed. Thanks to @sigaloid for pointing this out!
