Introduction

|
|
<p>Native applications that wish to integrate Waku may not be able to use nwaku and its JSON RPC API due to constraints
|
|
on packaging, performance or executables.</p>
|
|
<p>An alternative is to link existing Waku implementation as a static or dynamic library in their application.</p>
|
|
<p>This specification describes the C API that SHOULD be implemented by native Waku library and that SHOULD be used to
|
|
consume them.</p>
|
|
<h1 id="design-requirements">

|
Design requirements
|
|
<a class="anchor" href="#design-requirements">#</a>
|
|
</h1>
|
|
<p>The API should be generic enough, so:</p>
|
|
<ul>
|
|
<li>it can be implemented by both nwaku and go-waku C-Bindings,</li>
|
|
<li>it can be consumed from a variety of languages such as C#, Kotlin, Swift, Rust, C++, etc.</li>
|
|
</ul>
|
|
<p>The selected format to pass data to and from the API is <code>JSON</code>.</p>
|
|
<p>It has been selected due to its widespread usage and easiness of use. Other alternatives MAY replace it in the future (C
|
|
structure, protobuf) if it brings limitations that need to be lifted.</p>

<p>All the API functions return a <code>JsonResponse</code> unless specified otherwise.

<code>JsonResponse</code> is a <code>char *</code> whose format depends on whether the function was executed successfully or not.</p>
