Module content 

Content blocks: the building blocks of message bodies and stream deltas.

ContentBlock is the public, forward-compatible enum: it wraps a KnownBlock for any block type the SDK understands, or a raw serde_json::Value for any block type it doesn’t. This means an SDK older than the API will keep round-tripping payloads instead of panicking on a new variant.

Forward-compat semantics

• Unknown type tag → ContentBlock::Other preserving the JSON byte-for-byte.
• Known type tag with malformed fields → deserialization error (we do not silently fall through, so genuine bugs surface).

use claude_api::messages::content::ContentBlock;

let json = serde_json::json!({"type": "text", "text": "hi"});
let block: ContentBlock = serde_json::from_value(json).unwrap();
assert_eq!(block.type_tag(), Some("text"));
