Stdlib module compression/huffman.vitl

This page is a wiki-style reference for one concrete stdlib file. It explains what the file owns, where it fits in the family, and how to decide whether this is the right surface to depend on.

`compression/huffman.vitl` is a public stdlib surface inside the `compression` family. It should be read as one focused slice of the broader family responsibility: Algorithms and interfaces for compacting data: huffman, lz, deflate, brotli, stats, and shared compression interfaces.

Purpose

This file should be chosen because of responsibility, not because its name “sounds close enough”. Inside the compression family, it carries one focused part of the contract and keeps that responsibility separate from neighboring concerns.

  • A report archive can be built in memory, then compressed before emission.
  • A transport layer can separate serialization from compression instead of mixing both in one procedure.

Imported surfaces

This file does not advertise a top-level `use` surface in its opening declarations. That often means it is either self-contained or an aggregation layer.

How to use this module

Start by reading the file as an ownership boundary. Ask three questions: what enters this module, what stable types or procedures it exports, and what adjacent module should stay outside of it.

  1. Open the family page first to understand why this area of the stdlib exists.
  2. Read the source excerpt below to see the namespace, imports, and first declared surfaces.
  3. Check the neighbor list to avoid coupling this module with an adjacent responsibility by habit.

The excerpt is not meant to replace the file. It exists to make the module recognizable at first glance, the same way a Wikipedia infobox helps the reader orient before reading the whole article.

Integration boundaries

Within compression, this file should remain focused. If a future helper changes the host boundary, scheduling boundary, or data-shape boundary, it probably belongs in a neighbor module instead of being added here by convenience.

  • Family responsibility: Algorithms and interfaces for compacting data: huffman, lz, deflate, brotli, stats, and shared compression interfaces.
  • Family architecture role: Use `compression` when compactness is a first-class requirement and the program must explain which algorithmic boundary owns that transformation.
