dpp-plugin-sdk

Guest-side SDK and ABI export macro for Odal Node Wasm sector plugins. This crate provides the glue and helper utilities that make writing a Wasm sector plugin straightforward: a single export_plugin! macro generates the linear-memory ABI (alloc/dealloc) and the standard exports (metadata, describe, validate, calculate_metrics, generate_passport).

When to use this crate

You are authoring a Wasm sector plugin and want the standard host/guest ABI wiring without hand-rolling alloc/dealloc and JSON packing.
You need the helper functions that serialise/deserialise the Plugin* types defined in dpp-plugin-traits and want to reuse the same dpp_rules implementation as the host.

Example

use dpp_plugin_sdk::{export_plugin, traits::*};

#[derive(Default)]
struct BatteryPlugin;

impl DppSectorPlugin for BatteryPlugin {
    // implement `meta`, `capabilities`, `validate_input`, `calculate_metrics`, `generate_passport`
}

export_plugin!(BatteryPlugin);

Relationship to other crates

Crate	Role
`dpp-plugin-traits`	Defines the host/guest contract (`PluginMeta`, `PluginCapabilities`, `DppSectorPlugin`)
`dpp-rules`	Re-exported rule implementations so plugins share the same rules engine as the host
