//! Schema Management for Message and Stateful Storage
//!
//! ## Quick Links
//! - [Configuration: `Config`](Config)
//! - [Extrinsics: `Call`](Call)
//! - [Runtime API: `SchemasRuntimeApi`](../pallet_schemas_runtime_api/trait.SchemasRuntimeApi.html)
//! - [Custom RPC API: `SchemasApiServer`](../pallet_schemas_rpc/trait.SchemasApiServer.html)
//! - [Event Enum: `Event`](Event)

#![doc = include_str!("../README.md")]
//!
//! ## Implementations
//!
//! - [`SchemaValidator`](../common_primitives/schema/trait.SchemaValidator.html): Functions for accessing and validating Schemas. This implementation is what is used in the runtime.
//! - [`SchemaProvider`](../common_primitives/schema/trait.SchemaProvider.html): Allows another pallet to resolve schema information.
