AVM Runner interface

AVM Runner is the abstraction over Aqua virtual machine (AVM) interpreter designed to allow run it in different contexts such as web workers in browsers or worker threads on nodejs.

The package provides common interface for AVM runner implementation as well as necessary TypeScript definitions.

Getting started

The main exports of the package is the AVM runner type :

export type AvmRunner = {
    init: (logLevel: LogLevel) => Promise<void>;
    terminate: () => Promise<void>;
    run: (
        air: string,
        prevData: Uint8Array,
        data: Uint8Array,
        params: {
            initPeerId: string;
            currentPeerId: string;
        },
        callResults: CallResultsArray,
    ) => Promise<InterpreterResult>;
};

To make a custom AVM runner three functions has to be implemented:

• init - should allocate any resources needed for AVM runner (such as AVM interpreter memory or background worker state)
• terminate - should deallocate all the resources used by the AVM runner
• run - should pass the particle execution to actual AVM interpreter running in the context of implementation

Available implementations:

• Single-threaded, ui-blocking: @fluencelabs/avm-runner
• Web workers based for browsers: @fluencelabs/avm-runner-web
• Worker threads based for nodejs: @fluencelabs/avm-runner-node
