Stdlib module compression/interface.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/interface.vitl.Family: compression
Kind: public stdlib surface
Page style: this reference follows the same “encyclopedic card + portrait + usage contract” logic as the keyword pages, but for stdlib modules.

`compression/interface.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.

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

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.
