Crate chio_core_types 

Core Chio protocol types: capabilities, receipts, crypto primitives, and canonical JSON. This crate is no_std + alloc compatible; heavier domain crates (chio-core, chio-appraisal, etc.) re-export these types with additional features layered on top.

no_std support

The crate is no_std + alloc by source: under --no-default-features every module compiles against core and alloc only. This is the foundation that lets chio-kernel-core cross-compile to wasm32-unknown-unknown and other embedded targets. The default std feature re-enables std-backed error impls via thiserror, along with the std feature on every transitive dependency.

Generated wire bindings

Schema-derived Rust bindings live under src/_generated/ as regenerate-only artifacts. They are not re-exported from this crate root: the stable public API is the hand-maintained no_std-compatible protocol modules below.
