source · [−]

pub enum ItemValue {
    Text(String),
    Locator(String),

}

Expand description

Represents a tag item’s value

Variants

`Text(String)`

Any UTF-8 encoded text

`Locator(String)`

Any UTF-8 encoded locator of external information

This is only gets special treatment in ID3v2 and APE tags, being written as a normal string in other tags

`Binary(Vec<u8>)`

Binary information
