Examples

Reading tag frames

use id3::{Tag, TagLike};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let tag = Tag::read_from_path("testdata/id3v24.id3")?;

    // Get a bunch of frames...
    if let Some(artist) = tag.artist() {
        println!("artist: {}", artist);
    }
    if let Some(title) = tag.title() {
        println!("title: {}", title);
    }
    if let Some(album) = tag.album() {
        println!("album: {}", album);
    }

    // Get frames before getting their content for more complex tags.
    if let Some(artist) = tag.get("TPE1").and_then(|frame| frame.content().text()) {
        println!("artist: {}", artist);
    }
    Ok(())
}

Modifying any existing tag

use id3::{Error, ErrorKind, Tag, TagLike, Version};
use std::fs::copy;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let temp_file = std::env::temp_dir().join("music.mp3");
    copy("testdata/quiet.mp3", &temp_file)?;

    let mut tag = match Tag::read_from_path(&temp_file) {
        Ok(tag) => tag,
        Err(Error{kind: ErrorKind::NoTag, ..}) => Tag::new(),
        Err(err) => return Err(Box::new(err)),
    };

    tag.set_album("Fancy Album Title");

    tag.write_to_path(temp_file, Version::Id3v24)?;
    Ok(())
}

Creating a new tag, overwriting any old tag

use id3::{Tag, TagLike, Frame, Version};
use id3::frame::Content;
use std::fs::copy;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let temp_file = std::env::temp_dir().join("music.mp3");
    copy("testdata/quiet.mp3", &temp_file)?;

    let mut tag = Tag::new();
    tag.set_album("Fancy Album Title");

    // Set the album the hard way.
    tag.add_frame(Frame::text("TALB", "album"));

    tag.write_to_path(temp_file, Version::Id3v24)?;
    Ok(())
}

Handling damaged or files without a tag

use id3::{Tag, TagLike, partial_tag_ok, no_tag_ok};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let tag_result = Tag::read_from_path("testdata/id3v24.id3");

    // A partially decoded tag is set on the Err. partial_tag_ok takes it out and maps it to Ok.
    let tag_result = partial_tag_ok(tag_result);

    // no_tag_ok maps the NoTag error variant and maps it to Ok(None).
    let tag_result = no_tag_ok(tag_result);

    if let Some(tag) = tag_result? {
      // ..
    }

    Ok(())
}

Do you think you have found a bug? Then please report it via the GitHub issue tracker. Make sure to attach any problematic files that can be used to reproduce the issue. Such files are also used to create regression tests that ensure that your bug will never return.

When submitting pull requests, please prefix your commit messages with fix: or feat: for bug fixes and new features respectively. This is the Conventional Commits scheme that is used to automate some maintenance chores such as generating the changelog and inferring the next version number.
