rahmen-exiv2

A minimal, safe wrapper over libexiv2, built for rahmen.

It exposes only the read-only image-metadata operations rahmen needs — opening an image and reading a single Exif/Iptc/Xmp tag as an interpreted (human-readable) string — through a small C++ shim bound with cxx. The unavoidable FFI unsafe is confined to this crate, so dependents can keep #![forbid(unsafe_code)].

Requirements

• libexiv2 development files (e.g. libexiv2-dev on Debian/Ubuntu); discovered at build time via pkg-config. exiv2 0.27 and 0.28 are both supported.
• A C++17 compiler.

Example

use rahmen_exiv2::Metadata;

let meta = Metadata::new_from_path("image.jpg")?;
let when = meta.get_tag_interpreted_string("Exif.Photo.DateTimeOriginal")?;
println!("{when}");
# Ok::<(), rahmen_exiv2::Exiv2Error>(())
