TUI from Zero

О курсе

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.
