Crate icydb 

icydb

icydb is the public facade crate for the IcyDB runtime. It is the recommended dependency for downstream canister projects.

This crate exposes:

• the stable runtime surface used inside canister actor code,
• schema and design-time helpers for macros and validation,
• and a small set of macros and entry points that wire generated code.

Low-level execution, storage, and engine internals live in icydb-core and are re-exposed selectively through stable facade modules.

Crate layout

• base Design-time helpers, sanitizers, and validators used by schemas and macros.

• build Internal code generation helpers used by macros and tests (not intended for direct use).

• traits / types / value / visitor Stable runtime and schema-facing building blocks used by generated code.

• model / metrics (internal) Runtime model and metrics internals. Exposed for advanced tooling only; not part of the supported semver surface.

• error Shared error types for generated code and runtime boundaries.

• macros Derive macros for entities, canisters, and schema helpers.

• schema Schema AST, builders, and validation utilities.

• db The public database façade: session handles, query builders, and typed responses.

Preludes

• prelude Opinionated runtime prelude for canister actor code. Intended to be glob-imported in lib.rs to keep endpoints concise.

• design::prelude Prelude for schema and design-time code (macros, validators, and base helpers).

Internal boundaries

Generated code targets explicit facade surfaces (traits, patch, and __macro) instead of a broad internal-export module.
