The MetadataBuilder is responsible for managing metadata items in an EPUB publication. Metadata includes essential information such as title, author, language, identifier, publisher, and other descriptive information about the publication.

§Required Metadata

According to the EPUB specification, the following metadata are required:

  • title: The publication title
  • language: The language of the publication (e.g., “en”, “zh-CN”)
  • identifier: A unique identifier for the publication with id “pub-id”

Implementations§

§Parameters
  • item: The metadata item to add
§Return
  • &mut Self: Returns a mutable reference to itself for method chaining
Source

pub fn clear(&mut self) -> &mut Self

Clear all metadata items

Removes all metadata items from the builder.
