Crate canic 

Canic facade crate.

This crate is the recommended dependency for downstream canister projects. It re-exports the core Canic stack and provides the common macro entry points:

• build! / build_root! for build.rs (validate/embed canic.toml)
• start! / start_root! for lib.rs (wire lifecycle hooks and export endpoints)

For lower-level access, use the api, cdk, memory, and utils modules. Direct access to internal core modules is intentionally unsupported.

Re-exports

pub use canic_cdk as cdk;

pub use canic_utils as utils;
