## What it is
A Rust crate providing typed distributed plugin registration, allowing plugins to be registered into a registry from any source file linked into an application without a central list. It uses macros like collect! and submit! to gather statically registered values at link time.

## Use cases
- register command line flags from any source file without a central list
- build a plugin registry that downstream crates can contribute to
- avoid merge conflicts in large-scale codebases with distributed registration
- iterate over all statically registered plugin instances at runtime
- collect implementations or extensions across multiple crates

## When to choose
- you need distributed registration of typed values across crates in Rust
- you want to avoid maintaining a central list of plugins or flags
- you are building extensible frameworks or CLI flag systems in Rust

## When to avoid
- you need runtime dynamic plugin loading from shared libraries
- your project is not written in Rust
- you need plugins registered conditionally at runtime rather than statically

## Facets
- artifact type: library
- maturity: stable
- function: plugin-system, serialization
- domain: developer-tools, programming-languages
- platform: rust, cross-platform
- tags: distributed-registration, static-initialization, rust-crate, linkage, automation
