Component Documentation

Every page of the Slint documentation has a Markdown version, ~10x smaller. Replace a link's trailing slash with .md: this page is /master/docs/safety/component-documentation.md. /master/docs/safety/llms.txt lists all pages.

Addresses: ISO 26262-8 12.5.1, from 12.4.2.1

The slint-sc runtime ships inside the customer’s binary, so it’s qualified as a software component rather than as a tool. This document is its specification. The Component Qualification Plan says how it’s qualified. The Component Qualification chapter of the Qualification Report records the outcome.

• Safety Analysis: what can go wrong in the runtime, and the measure or constraint that covers each error.

Specification

12.4.2.1 asks the specification of the component to include the following.

Item	Where
a) Unique identification	The slint-sc crate from api/slint-sc, of the release under qualification
b) Maximum target ASIL	ASIL B; see Integrity Level
c) Qualification activities	Component Qualification Plan
d) Requirements of the component	The rendering model and the generated code contract, one identified paragraph per requirement
e) Requirements of the intended use	User Manual
f) Configuration	The crate has no features and no dependencies, so it has one configuration
g) Interfaces and shared resources	The slint-sc Runtime API, and the frame buffer the application owns; see Architecture Design
h) Application manual	User Manual
i) Integration instructions	Add the Runtime in the User Manual
j) Reactions under anomalous operating conditions	Safety Analysis; a frame buffer of the wrong size is rejected per sls.gen.render-error
k) Known anomalies and workarounds	Known Problems
