Characters to use when rendering the diagnostic.

By using Chars::ascii() you can switch to an ASCII-only format suitable for rendering on terminals that do not support box drawing characters.

The character to use for the left border break of the source. Defaults to: '·' or '.' with Chars::ascii().

note_bullet: char

The character to use for the note bullet. Defaults to: '='.

single_primary_caret: char

The character to use for marking a single-line primary label. Defaults to: '^'.

single_secondary_caret: char

The character to use for marking a single-line secondary label. Defaults to: '-'.

multi_primary_caret_start: char

The character to use for marking the start of a multi-line primary label. Defaults to: '^'.

Implementations

impl Chars

pub fn box_drawing() -> Chars

A character set that uses Unicode box drawing characters.

pub fn ascii() -> Chars

A character set that only uses ASCII characters.

This is useful if your terminal’s font does not support box drawing characters well and results in output that looks similar to rustc’s diagnostic output.

Trait Implementations

impl Clone for Chars

fn clone(&self) -> Chars

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Chars

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

Formats the value using the given formatter.

impl Default for Chars

fn default() -> Chars

Returns the “default value” for a type.
