Module dump_writer 

Writer for Rust-native kernel dump files Writer for Rust-native kernel dump files.

Serializes the State diff (from snapshot/diff_from_snapshot) into a compact text format that can be loaded back efficiently.

This is the “DumpFile” equivalent from Perl’s TeX_Job.pool.ltxml. The workflow follows Perl’s Makefile.PL “make formats” scaffold:

1. take_snapshot() — before processing latex.ltx
2. Process latex.ltx through the engine
3. diff_snapshot() — find what changed
4. write_dump() — serialize the diff
5. At runtime: load_dump() restores the state

Functions

write_dump

Write a state diff to a dump file. Returns the number of entries successfully written.
