Crate slick 

slickit — Semantic, LLM-Interpretable Component Kit.

Two layers, both in-memory:

Layer	Feature	Types	Consumer
Runtime	default	TypedStruct, TypedRegistry, RegistryError	geist-edge
Authoring	manifest	[Manifest]	Composer

Bridge: Manifest.type_url = TypedStruct.type_url.

Example (runtime layer)

use slick::{TypedStruct, TypedRegistryBuilder};

let registry = TypedRegistryBuilder::<String, String>::new()
    .register("example.v1", |value| {
        let name: String = serde_json::from_value(value.clone())
            .map_err(|e| e.to_string())?;
        Ok(name)
    })
    .build();

let val = serde_json::json!("hello");
let instance = registry.create("example.v1", &val).unwrap();
assert_eq!(instance, "hello");

Structs

TypedRegistry

Immutable typed registry. Maps type URL → factory.

TypedRegistryBuilder

Mutable builder for TypedRegistry. Immutable after build().

TypedStruct

Typed structured data envelope — a type URL plus an opaque value.

Enums

RegistryError

Error returned by TypedRegistry::create and TypedRegistry::create_all.
