Trait Implementations

impl Clone for EpubMetadata

fn clone(&self) -> EpubMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpubMetadata

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

Formats the value using the given formatter.

impl Default for EpubMetadata

fn default() -> Self

Returns the “default value” for a type.
