TimelineItem

TimelineItem is the event record used by Timeline.

Each item represents one moment or milestone in a sequence, such as an activity log entry, message event, deployment step, or support history item.

Example

use fission::prelude::*;

let item = TimelineItem {
    title: "Build finished".into(),
    description: Some("All checks passed on main.".into()),
    timestamp: Some("10:24".into()),
};

Field table

Field	Type	Meaning	Notes / default behavior
title	String	Main event label.	Required.
description	Option<String>	Supporting explanation below the title.	Defaults to None.
timestamp	Option<String>	Optional time or date label.	Defaults to None. Format it upstream.

Specific advice

Keep timestamps human-readable and consistent across items. A timeline becomes harder to scan if each item uses a different date or time format.

Production checklist

For TimelineItem, review the fields that change behavior before treating the widget as finished: title, description, timestamp. The goal is to make the product rule visible in state and actions, not hidden inside ad-hoc construction code.

•

If this widget appears inside an interactive flow, keep the surrounding action binding in the parent component and test that the flow still has one clear reducer path.

•

Check the semantics tree for the user-facing label or role that makes this widget understandable without relying only on pixels.

•

Add at least one component or harness test that confirms the visible text, semantic role, action dispatch, and layout constraint that matter for this widget in context.

If a screen starts repeating the same TimelineItem setup, extract a named component around this widget. That keeps the reference API small while making product code easier to read and safer for generated code to copy.
