Struct Json 

pub struct Json { /* private fields */ }

A parsed JSON document, rendered with syntax highlighting. Mirrors rich.json.JSON.

Implementations

impl Json

pub fn new(text: &str) -> Result<Self>

Parse text as JSON. Returns an error if it is not valid JSON.

pub fn no_wrap(self, no_wrap: bool) -> Self

Keep rich.json.JSON’s self.text.no_wrap = True, which crops each line at the available width instead of wrapping it.

Defaults to false, because that is what a top-level Console.print(JSON(...)) produces and that is how this renderable is normally reached. Upstream’s flag really is set, but Console.print never renders the Text it is set on: _collect_renderables sees a Text, buffers it, and check_text hands back Text(sep, justify=…, end=…).join(buffered) — and Text.join starts from self.blank_copy(), i.e. from the separator’s metadata. The separator has no_wrap=None, so the copy that actually renders wraps with the default fold overflow.

Turn it on whenever the document is nested inside another renderable — a Panel, Padding, Styled, Constrain, or rich-cli’s ForceWidth. Those are ConsoleRenderables, so _collect_renderables appends them untouched and the inner Text reaches Text.__rich_console__ with the flag intact; Text.wrap then skips divide_line and only truncates to the width.

The two are not interchangeable. Wrapping keeps every character; cropping discards what does not fit, which for JSON means the printed document no longer parses — so the choice has to follow upstream’s, not taste.

Trait Implementations

impl Renderable for Json

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.
