Struct GraphicalRenderer 

pub struct GraphicalRenderer {
    pub theme: Theme,
    pub width: usize,
    pub padding: usize,
    pub gutter_margin: usize,
    pub context_lines: usize,
    pub use_colors: bool,
    pub highlight_source: bool,
    /* private fields */
}

An implementation of Renderer which displays diagnostics in a graphical way in the console using colors, Unicode symbols and highlighting.

Examples

use error_snippet::{Renderer, GraphicalRenderer};

let renderer = GraphicalRenderer::new();

Fields

theme: Theme

Defines the theme of the renderer.

The theme defines which colors and symbols to use when rendering diagnostics.

context_lines: usize

Defines the amount of lines surrounding a label to include as context.

use_colors: bool

Defines whether to use colors in the output.

highlight_source: bool
