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);

Modifying any existing tag.

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

fn main() -> Result<(), Box<dyn std::error::Error>> {
    copy("testdata/quiet.mp3", "/tmp/music.mp3")?;

    let mut tag = match Tag::read_from_path("/tmp/music.mp3") {
        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("/tmp/music.mp3", Version::Id3v24)?;

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>> {
    copy("testdata/quiet.mp3", "/tmp/music.mp3")?;

    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("/tmp/music.mp3", Version::Id3v24)?;


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.



  • Contains types and methods for operating on ID3 frames.
  • Utilities for working with ID3v1 tags.
  • Combined API that handles both ID3v1 and ID3v2 tags at the same time.


  • The Encoder may be used to encode tags with custom settings.
  • A structure able to represent any error that may occur while performing metadata operations.
  • An ID3 tag containing zero or more Frames.


  • Types of text encodings used in ID3 frames.
  • Kinds of errors that may occur while performing metadata operations.
  • Denotes the version of a tag.


  • TagLike is a trait that provides a set of useful default methods that make manipulation of tag frames easier.


  • Takes a tag result and maps any partial tag to Ok. An Ok result is left untouched. An Err without partial tag is returned as the initial error.

Type Aliases

  • Type alias for the result of tag operations.
