Struct Constrain 

pub struct Constrain { /* private fields */ }

Constrain the width of a renderable to a given number of characters.

Implementations

impl Constrain

pub fn new(renderable: impl Renderable + 'static, width: Option<usize>) -> Self

Create a Constrain wrapper around any renderable.

If width is None, this is a pass-through wrapper (matches Python Rich behavior).

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

Create a Constrain wrapper around a boxed renderable.

pub fn new_measurable( renderable: impl Renderable + RichMeasure + 'static, width: Option<usize>, ) -> Self

Create a Constrain wrapper around a renderable that supports measurement.

pub const fn width(self, width: Option<usize>) -> Self

Set / clear the constrain width.

Trait Implementations

impl Debug for Constrain

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Renderable for Constrain

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

Render the object to a list of segments.

impl RichMeasure for Constrain

fn rich_measure( &self, console: &Console, options: &ConsoleOptions, ) -> Measurement

Measure minimum and maximum width requirements for a renderable.
