Struct DiffView 

pub struct DiffView { /* private fields */ }

A line diff as a renderable: unified (default) or side by side, with line numbers, hunk headers and word-level emphasis on changed lines.

use rich::Console;
use rich_ext::diff::DiffView;

let console = Console::builder().width(40).no_color(true).build();
let out = console.render_to_string(&DiffView::new("a\nb\n", "a\nc\n").line_numbers(false));
assert_eq!(out, "@@ -1,2 +1,2 @@\n  a\n- b\n+ c");

Implementations

impl DiffView

pub fn new(old: &str, new: &str) -> Self

Diff two plain texts.

pub fn from_diff(diff: &TextDiff) -> Self

View an existing TextDiff, keeping its context setting.

pub fn ansi(old: &str, new: &str) -> Self

Diff two ANSI-styled texts. Lines are compared by their visible text; lines with the same text but different styling are reported as style-only changes (~). Each side keeps its own styling.

pub fn snapshots(old: &RenderSnapshot, new: &RenderSnapshot) -> Self

Diff two render snapshots through their ANSI output, so styling regressions show as ~ lines.

pub fn layout(self, layout: Layout) -> Self

Unified (default) or side by side.

pub fn line_numbers(self, show: bool) -> Self

Show line numbers (default on).

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

Wrap long lines (default) or truncate them with an ellipsis.

pub fn context(self, lines: usize) -> Self

Unchanged lines around each change (default 3).

pub fn titles(self, old: impl Into<String>, new: impl Into<String>) -> Self

Titles for the old and new sides (---/+++ when unified, column headings side by side).

pub fn emphasis(self, on: bool) -> Self

Word-level emphasis on changed lines (default on).

pub fn is_equal(&self) -> bool

Whether the two sides render identically.

pub fn stats(&self) -> (usize, usize, usize)

(added, removed, restyled) line counts.

pub fn style_changed_lines(&self) -> Vec<usize>

The 1-based new-side lines whose text matches but styling differs.

Trait Implementations

impl Clone for DiffView

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DiffView

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

Formats the value using the given formatter.

impl Renderable for DiffView

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. Port of __rich_measure__. The default is what upstream’s Measurement.get returns for a renderable without one: anything from nothing to the whole width, (0, max_width).

fn fit_to_measurement(&self) -> bool

Whether a top-level Console::print shrinks this renderable to its measured width. Upstream renders every top-level renderable at the full console width, so the default is false; an extension may opt in.

fn vertical(&self) -> Option<VerticalAlign>

The vertical alignment a Table cell holding this renderable uses in place of its column’s. Upstream reads getattr(renderable, "vertical", None); Align sets it.

fn print_end_line(&self, _options: &ConsoleOptions) -> bool

Whether a top-level print ends this renderable’s last line. This port’s renderables separate lines, where upstream’s end each line with "\n", so a print adds the final line break. A renderable whose upstream output stops without one (Screen, LiveRender, a Rule whose end has no newline) returns false, and the next output continues its last line. options are the print’s options.
