Crate rexiv2 [] [src]

This library provides a Rust wrapper around the gexiv2 library, which is itself a GObject-based wrapper around the Exiv2 library, which provides read and write access to the Exif, XMP, and IPTC metadata for media files in various formats.

Most functionality is exposed through methods on the Metadata type.

Usage

A typical use of the library might look something like this:

let file = "myimage.jpg";
let tag = "Iptc.Application2.Keywords";
let meta = rexiv2::Metadata::new_from_path(&file).unwrap();
println!("{:?}", meta.get_tag_multiple_strings(tag));
