Implementations

impl KnownMetadata

pub fn is_cdrom(tag: u32) -> bool

Returns whether a given tag indicates that the CHD contains CDROM data.

Trait Implementations

impl Clone for KnownMetadata

fn clone(&self) -> KnownMetadata

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
