Crate ucm_core 

UCM Core

Core types and traits for the Unified Content Model (UCM).

This crate provides the fundamental building blocks for representing structured content in a graph-based intermediate representation.

Key Types

• Block - The fundamental unit of content
• BlockId - Content-addressed identifier with 96-bit collision resistance
• Content - Typed content (text, table, code, etc.)
• Document - A collection of blocks with hierarchical structure
• Edge - Explicit relationships between blocks

Example

use ucm_core::Content;
use ucm_core::id::generate_block_id;

let content = Content::text("Hello, UCP!");
let id = generate_block_id(&content, Some("intro.hook"), None);
println!("Block ID: {}", id);
