# That's It!
|
||||
|
||||
Minimal, cross-environment user interface framework.
|
||||
|
||||
## Definitions
|
||||
|
||||
### User interface
|
||||
|
||||
A **user interface** is a program which, repeatedly:
|
||||
* **renders** information to be displayed to the user;
|
||||
* **handles** input from the user;
|
||||
thus interactively performing tasks until an exit condition is met.
|
||||
|
||||
### Engine
|
||||
|
||||
An **engine** is the underlying platform responsible for:
|
||||
* Displaying your program's `render`ed output to the user
|
||||
* Reading user input to be `handle`d by your program.
|
||||
|
||||
For example, the `tui` engine is based on `crossterm`,
|
||||
a library for rendering text user interfaces.
|
||||
|
||||
### Widget
|
||||
|
||||
A **widget** is any struct that implements the `Input<E, I>` and `Output<E, O>`
|
||||
traits for a given engine `E`. This enables it to act as a component of the
|
||||
user interface. Widgets may contain arbitrary state -- including other widgets.
|
||||
We provide a set of basic widgets that allow you to define standard hierarchical
|
||||
UI layouts. It's the implementor's responsibility to define
|
||||
`render` and `handle` behaviors for custom widgets.
|
||||
|
||||
### Input
|
||||
|
||||
**To respond to user input**, implement the trait `Input`.
|
||||
It has a single method, `handle`, which takes an input
|
||||
event, and returns an engine-specific value.
|
||||
|
||||
In the case of the `tui` engine, the returned value is a
|
||||
`bool` corresponding to whether the input event was captured
|
||||
by the current widget. Returning `true` from `render` terminates
|
||||
the handling of the current event; returning `false` "bubbles" it
|
||||
to the parent widget.
|
||||
|
||||
### Output
|
||||
|
||||
**To display data to the user**, implement the trait `Output`.
|
||||
It has a single method, `render`, which takes a mutable instance
|
||||
of the engine, and returns and engine-specific value.
|
||||
|
||||
In the case of the `tui` engine, the returned value is `[u16;2]`,
|
||||
corresponding to the size requested by the widget. This allows
|
||||
the layout components to implement dynamic, responsive layouts in the
|
||||
terminal.
