Struct Constrain 

pub struct Constrain { /* private fields */ }

Limits a child renderable to at most width cells. Mirrors rich.constrain.Constrain.

Implementations

impl Constrain

pub fn new(child: Box<dyn Renderable>, width: Option<usize>) -> Self

Constrain child to width cells (or leave unconstrained when None).

Trait Implementations

impl Renderable for Constrain

fn rich_render( &self, console: &Console, options: &ConsoleOptions, ) -> Vec<Segment>

fn measure(&self, _console: &Console, options: &ConsoleOptions) -> Measurement

The (minimum, maximum) cell width this renderable wants. The default assumes the renderable fills the available width (e.g. Panel, Table); Text overrides it with its content width so the top-level print path can shrink to fit. Port of __rich_measure__ / Measurement.get.

fn fit_to_measurement(&self) -> bool

Whether a top-level Console::print shrinks this renderable to its measured width. The shrink stands in for upstream’s _collect_renderables, which joins printed str/Text values; other upstream renderables render at the full width, so one whose output pads to the width it is given (Syntax’s background) returns false.
