Module runtime 

Running applications: the App trait, Commands, the terminal Runtime and the test Harness.

Structs

Command

Work for the runtime, returned from App::update.

Confirm

A question for Command::confirm: a title, an optional message, and the messages for the answers.

DetachedHandoff

Hands the terminal to a program until it writes its first line on standard output, then takes the screen back and leaves the program running in the background as a LiveChild.

FrameLimit

How many frames a second the runtime draws at most, for a local and for a remote connection.

Handoff

Hands the terminal to another program: leaves raw mode and the alternate screen, runs it attached to the real terminal, then takes the screen back and draws everything again.

HandoffRequest

A handoff a Harness recorded instead of running.

Harness

Runs an App against an in-memory screen.

LiveChild

A program a DetachedHandoff left running: its standard input is the application’s to write, its later output arrives as messages through DetachedHandoff::on_line.

Process

A child process whose output is read line by line, for showing in a log view.

Runtime

Configures and runs an application in the terminal.

Task

Work to run in the background with progress, cancellation and an outcome.

TaskCx

What running work can do: report progress, send messages, notice cancellation and sleep.

TaskEntry

One task as the application shows it.

TaskId

Identifies one task for its whole life. Ids are unique within the process.

Tasks

Tasks an application shows, kept up to date with Tasks::apply. Newest last.

TestChild

The test’s side of the stand-in from LiveChild::for_tests: it plays the program.

Enums

ChildLine

What a LiveChild says, delivered through DetachedHandoff::on_line.

ClipboardEvent

Something that happened on the clipboard, delivered to App::clipboard.

DetachedOutcome

How a DetachedHandoff ended.

HandoffOutcome

How a handoff ended.

Line

Where a line came from. With a pseudo-terminal both streams share one line, so only Line::Out appears.

ProcessOutcome

How the child ended.

TaskEvent

What happened to a task, delivered through Task::on_event.

TaskOutcome

How a task ended.

Termination

Why the system, rather than the user, is ending the application.

Traits

App

An application built with quvyta-framework: data, a function that draws it and a function that changes it.

Functions

html_page

Wraps Harness::html fragments in an HTML document that lays screens out on a dark page.
