Struct RenderOptions 

pub struct RenderOptions {
    pub crop_radius: usize,
    pub color: bool,
}

Caller-controlled rendering options for Error::render_with_options.

Defaults to crop_radius = 2 and color = false so the stable byte-for-byte CI-friendly output stays the default. Set color = true for interactive terminal use.

Construct directly with a struct literal — both fields are public. Future field additions are tracked as a minor-version event per the SemVer policy.

Examples

use noyalib::RenderOptions;
let default = RenderOptions::default();
assert_eq!(default.crop_radius, 2);
assert!(!default.color);

// Custom — single-line, coloured.
let custom = RenderOptions { crop_radius: 0, color: true };
assert_eq!(custom.crop_radius, 0);

Fields

crop_radius: usize

Number of source lines to include above and below the offending line. 0 collapses to a single-line render. Default 2 (rustc-style window).

color: bool

When true, the rendered output includes terminal ANSI colour escapes (red error:, blue gutter, yellow caret). Default false so CI logs and golden tests stay stable.

Implementations

impl RenderOptions

pub fn new() -> Self

Construct with all defaults (crop_radius = 2, color = false). Equivalent to RenderOptions::default().

Examples

use noyalib::RenderOptions;
let opts = RenderOptions::new();
assert_eq!(opts.crop_radius, 2);
assert!(!opts.color);

pub fn crop_radius(self, radius: usize) -> Self

Set the crop radius (lines of context on each side of the offending line). 0 collapses to a single-line render.

Examples

use noyalib::RenderOptions;
let opts = RenderOptions::new().crop_radius(4);
assert_eq!(opts.crop_radius, 4);

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

Toggle ANSI colour escape codes on rendered output.

Examples

use noyalib::RenderOptions;
let opts = RenderOptions::new().color(true);
assert!(opts.color);
