A snippet of getting the cover art (APIC frame) from a music file. For later use :)

rust_cover_art_extraction.rs

use eyre::{Context, ContextCompat, Report};
use id3::{Content, Tag, TagLike};
use image::ImageReader;
use std::{env, io::Cursor};

fn main() -> Result<(), Report> {
    color_eyre::install()?;
    get_cover_art(env::args().nth(1).unwrap().as_str())?;
    Ok(())
}

fn get_cover_art(path: &str) -> Result<(), Report> {
    let tag = Tag::read_from_path(path).wrap_err("Couldn't read tag")?;
    let apic_frame = tag.get("APIC").wrap_err("Couldn't get APIC frame")?;
    if let Content::Picture(cover) = apic_frame.content() {
        ImageReader::new(Cursor::new(&cover.data))
            .with_guessed_format()?
            .decode()?
            .save("cover.png")?;
    }

    Ok(())
}
