Crate canic_core

Expand description

Core Canic library used inside canisters.

Most users should depend on the canic facade crate, which re-exports this crate under canic::core and exposes the common entrypoint macros:

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

Canic is organized to keep endpoint code thin and policies centralized:

The default flow is: endpoints → workflow → policy → ops → model.
