Types Reference

Quick reference index for all Titan API types — links to the page where each type is defined.

All type definitions live inline on the page where they're used. This page is an index for quick navigation.

Field names are camelCase on the wire (MessagePack) unless otherwise specified. Rust SDK types use snake_case with serde renaming.
