Rust library for working with media file metadata
This crate provides a Rust wrapper around the gexiv2 library, which is a GObject-based wrapper around Exiv2, which provides read and write access to the Exif, XMP, and IPTC metadata in media files (typically photos) in various formats.
API documentation is available online.
Exiv2’s homepage has documentation on available namespaces and tags.
During development and testing, the Exiv2 command-line utility may come in handy.
Setup & Dependencies
rexiv2 requires Rust 1.63 or newer, and uses the 2021 edition of the language.
Being a wrapper for gexiv2 and Exiv2, rexiv2 obviously depends on them. These libraries are not bundled with rexiv2: you will need to install them separately.
gexiv2 is supported from version 0.10 onwards, and Exiv2 from version 0.23.
For full instructions on how to get started with rexiv2, including how to
install the prerequisite dependencies, refer to the
Note that if you want BMFF support (e.g. HEIC, HEIF, AVIF, CR3, JXL/bmff files) you will need an up-to-date version of the underlying libraries (at least gexiv2 v0.13.0 and Exiv2 v0.27.4). You will also need to ensure that your version of Exiv2 has BMFF support enabled. This is generally enabled by default, but may be switched off in certain distributions due to licensing issues.
Versioning & History
rexiv2 is currently available as a pre-1.0 development version.
Version numbers follow the principles of Semantic Versioning.
No further breaking API changes are planned, but they are possible as a result of feedback on the API as more users try it out. Such feedback is welcome, and having the API tried out in real applications is part of ensuring it’s ready for a 1.0 release.

This feature is disabled by default because it introduces a new dependency on
glib-sys, and consequently on the GLib system library.
