When will I have access to the lectures and assignments?

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

What will I get if I subscribe to this Specialization?

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Is financial aid available?

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.

Was Sie lernen werden

Build a pure-Rust terminal-UI framework from the cell buffer up, with byte-deterministic snapshot tests in CI.
Apply the Elm-style init/update/view shape and composite layout to build production widgets (CpuGrid, ProcessTable, MemoryBar).
Create ptop-mini end-to-end — a Snapshot-fixture-driven process monitor that swaps to a live /proc reader without changing the view function.

TUI from Zero teaches you to build a pure-Rust terminal-UI framework from first principles to a working ptop-mini process monitor. Across five modules, you'll learn the wire format of a terminal — cells, ANSI escape sequences, Unicode block elements, and Braille code points — and how CellBuffer and DiffRenderer turn those primitives into a zero-allocation steady state. You'll master the Elm-style init/update/view shape, composite layout with Container/Row/Column, the .prs declarative scene format, and probar snapshot testing so every render byte is deterministic in CI.

The capstone is ptop-mini, a Rust process monitor whose production binary swaps a Snapshot fixture for a live /proc reader without changing one line of the view function. Every widget is gated by a YAML contract and a probar snapshot test, so the framework you build is provable, not merely working. You should be comfortable with intermediate Rust — ownership and borrowing, traits and generics, Result and the ? operator. No prior terminal-UI experience is required.

Moduldetails

Build the rendering core of a Rust TUI from first principles. Learn how a terminal is a 2D grid of cells, how double-width Unicode is kept safe, why ANSI escape sequences are the wire format, and how CellBuffer and the Widget trait give you one paint(rect) method that composes everything else.

Wire user input to state through the Elm Architecture's three pure functions: init, update, and view. Model the counter app as a struct, define Msg as an exhaustive enum, and run crossterm's poll/read loop with raw mode. Map every KeyEvent through a total dispatch function so update never sees noise, and exit cleanly on Esc, Ctrl-C, or q.

Compose widgets that do real work — Sparklines from eight Unicode block glyphs, BrailleGraphs at 4x resolution, a CpuGrid that wraps one cell per core, a ProcessTable that scrolls, and a MemoryBar that fills. Each widget is one paint(rect) call; together they form a live system-monitor TUI.

Move from imperative paint calls to declarative scenes. Write .prs files that describe layout, then watch a 200-line recursive-descent compiler reconcile them against your widgets. Lock the look with probar snapshot tests — stringified CellBuffers, inline or file-backed goldens, byte-identical between runs, all running in CI without a TTY.

Bring everything together: a deterministic Snapshot fixture feeds a single pure view that composes CpuGrid, Sparkline, MemoryBar, and ProcessTable into one ptop-mini dashboard, then swap the fixture for a /proc reader to run the same view live.
