The tectonic_io_base create

This crate is part of the Tectonic project. It provides basic types for Tectonic’s pluggable I/O backend system, with implementations for std I/O types as well as flate2 gzip streams.

• API documentation.
• Main Git repository.

lib.rs:

Tectonic’s pluggable I/O backend.

This crates defines the core traits and types used by Tectonic’s I/O subsystem, and provides implementations for common stdlib types. It provides a simplified I/O model compatible with TeX’s usage patterns, as encapsulated in the IoProvider trait. Files are exposed as InputHandle or OutputHandle structs, which add a layer of bookkeeping to allow the higher levels of Tectonic to determine when the engine needs to be re-run.
