Crate quickexif

A rust library to parse EXIF data from images.

Why another EXIF parsing library?

Most EXIF libraries parse all the tags, whether they are needed or not, which consumes unnecessary memory and cpu resources. But quickexif parses the only needed tags to save computational resources during large-scale images EXIF extraction.

Example

let sample = std::fs::read("sample.JPG").unwrap();
let rule = quickexif::describe_rule!(tiff {
    0x010f {
        str + 0 / make
    }
    0x8769 {
        0xa002 / width
        0xa003 / height
    }
});
 
let parsed_info = quickexif::parse(&sample, &rule).unwrap();
 
let make = parsed_info.str("make").unwrap();
let width = parsed_info.u32("width").unwrap();
let height = parsed_info.u32("height").unwrap();
