Struct symphonia_core::meta::Metadata

pub struct Metadata<'a> { /* private fields */ }

A reference to the metadata inside of a MetadataLog.

Implementations

impl<'a> Metadata<'a>

pub fn is_latest(&self) -> bool

Returns true if the current metadata revision is the newest, false otherwise.

pub fn current(&self) -> Option<&MetadataRevision>

Gets an immutable reference to the current, and therefore oldest, revision of the metadata.

pub fn skip_to_latest(&mut self) -> Option<&MetadataRevision>

Skips to, and gets an immutable reference to the latest, and therefore newest, revision of the metadata.

pub fn pop(&mut self) -> Option<MetadataRevision>

If there are newer Metadata revisions, advances the MetadataLog by discarding the current revision and replacing it with the next revision, returning the discarded Metadata. When there are no newer revisions, None is returned. As such, pop will never completely empty the log.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
