Enum Style

pub enum Style {
    Error,
    Warning,
    Note,
    Help,
    Custom(char, char, Color),
}

Highlight format description.

Specifies how the highlight should be rendered:

• What character to use to underline highlights.

1 | fn main() {
2 |     println!("Hello World!")
  |              ^++++++++++++^ highlighting this string
3 | }

In this example, the underline character is +.

• What boundary marker character to use to point the first and last elements of a highlight.

1 |   fn main() {
  |  ___________^
2 | |     println!("Hello World!")
3 | | }
  | |_^ this span covers more than one line

In this example, the boundary marker is ^. Note that the underline character is not used.

Colors

If the colors feature is enabled, it is also possible to set a color to draw the lines. This will also make the highlights more bright (or bold), along with the line numbers.

Variants

Error

Warning

Yellow curvy underline.

Note

Blue straight underline.

Help

Green straight underline.

Custom(char, char, Color)

Custom highlight format.

Specifies the underline character, the boundary marker and the color (if the colors feature is enabled) used to render the highlight.
