Implementations of Tectonic bundle formats.

A Tectonic “bundle” is a collection of TeX support files. In code, bundles implement the Bundle trait defined here, although most of the action in a bundle will be in its implementation of tectonic_io_base::IoProvider.

This crate provides the following bundle implementations:


Local caching of bundle data.

A module for the directory bundle DirBundle.

The web-friendly “indexed tar” bundle backend.

ZIP files as Tectonic bundles.


A trait for bundles of Tectonic support files.


Open the fallback bundle.

Get the URL of the default bundle.
