Struct RootfileBuilder 

pub struct RootfileBuilder { /* private fields */ }

Rootfile builder for EPUB container

The RootfileBuilder is responsible for managing the rootfile paths in the EPUB container. Each rootfile points to an OPF (Open Packaging Format) file that defines the structure and content of an EPUB publication.

In EPUB 3.0, a single rootfile is typically used, but the structure supports multiple rootfiles for more complex publications.

Notes

• Rootfile paths must be relative and cannot start with “../” or “/”
• At least one rootfile must be added before building the EPUB

Implementations

impl RootfileBuilder

pub fn add(&mut self, rootfile: impl AsRef<str>) -> Result<&mut Self, EpubError>

Add a rootfile path

Adds a new rootfile path to the builder. The rootfile points to the OPF file that will be created when building the EPUB.

Parameters

• rootfile: The relative path to the OPF file

Return

• Ok(&mut Self): Successfully added the rootfile
• Err(EpubError): Error if the path is invalid (starts with “/” or “../”)

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

Clear all rootfiles

Removes all rootfile paths from the builder.

Trait Implementations

impl Debug for RootfileBuilder

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

Formats the value using the given formatter.
