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>> {
    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)?;
    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>> {
    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)?;
    Ok(())
}

Re-exports

pub use crate::frame::Frame;

Modules

Contains types and methods for operating on ID3 frames.

Utilities for working with ID3v1 tags.

Structs

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.

Represents a date and time according to the ID3v2.4 spec:

Enums

The decoded contents of a Frame.

Kinds of errors that may occur while performing metadata operations.

Denotes the version of a tag.

Traits

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

Functions

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 Definitions

Type alias for the result of tag operations.
