Function id3::partial_tag_ok

pub fn partial_tag_ok(rs: Result<Tag>) -> Result<Tag>

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.

Example

use id3::{Tag, Error, ErrorKind, partial_tag_ok};

let rs = Err(Error{
    kind: ErrorKind::Parsing,
    description: "frame 12 could not be decoded".to_string(),
    partial_tag: Some(Tag::new()),
});
assert!(partial_tag_ok(rs).is_ok());
