#![warn(unused_crate_dependencies)]

|
|
|
//! Defines primitive types for creating or validating a parachain.
|
|
//!
|
|
//! When compiled with standard library support, this crate exports a `wasm`
|
|
//! module that can be used to validate parachain WASM.
|
|
//!
|
|
//! ## Parachain WASM
|
|
//!
|
|
//! Polkadot parachain WASM is in the form of a module which imports a memory
|
|
//! instance and exports a function `validate_block`.
|
|
//!
|
|
//! `validate` accepts as input two `i32` values, representing a pointer/length pair
|
|
//! respectively, that encodes [`ValidationParams`].
|
|
//!
|
|
//! `validate` returns an `u64` which is a pointer to an `u8` array and its length.
|
|
//! The data in the array is expected to be a SCALE encoded [`ValidationResult`].
|
|
//!
|
|
//! ASCII-diagram demonstrating the return data format:
|
|
//!
|
|
//! ```ignore
|
|
//! [pointer][length]
|
|
//! 32bit 32bit
|
|
//! ^~~ returned pointer & length
|
|
//! ```
|
|
//!
|
|
//! The wasm-api (enabled only when `std` feature is not enabled and `wasm-api` feature is enabled)
|
|
//! provides utilities for setting up a parachain WASM module in Rust.
