Character set for rendering diagnostic output

Defines all the box-drawing and decorative characters used in rendering. Two predefined sets are available:

• CharSet::ascii() - Uses ASCII characters (-, |, +, etc.)
• CharSet::unicode() - Uses Unicode box-drawing characters (─, │, ┬, etc.)

You can also create custom character sets by modifying individual fields.

Example

let custom = CharSet {
    hbar: '=',
    vbar: '!',
    ..CharSet::ascii()
};

Fields

space: char

Space character (usually ’ ’)

newline: char

Newline representation (usually visible as box character)

lbox: char

Left box bracket (e.g., ‘[’)

rbox: char

Right box bracket (e.g., ‘]’)

colon: char

Colon separator (e.g., ‘:’)

hbar: char

Horizontal bar (e.g., ‘-’ or ‘─’)

vbar: char

Vertical bar (e.g., ‘|’ or ‘│’)

xbar: char

Cross bar (both horizontal and vertical)

vbar_break: char

Vertical bar with break

vbar_gap: char

Vertical bar with gap

uarrow: char

Upward arrow (e.g., ‘^’ or ‘↑’)

rarrow: char

Rightward arrow (e.g., ‘>’ or ‘→’)

ltop: char

Left top corner (e.g., ‘,’ or ‘╭’)

mtop: char

Middle top connector (e.g., ‘^’ or ‘┬’)

rtop: char

Right top corner (e.g., ‘.’ or ‘╮’)

lbot: char

Left bottom corner (e.g., ‘`’ or ‘╰’)

mbot: char

Middle bottom connector (e.g., ‘v’ or ‘┴’)

rbot: char

Right bottom corner (e.g., ‘'’ or ‘╯’)

lcross: char

Left cross connector (e.g., ‘+’ or ‘├’)

rcross: char

Right cross connector (e.g., ‘+’ or ‘┤’)

underbar: char

Underbar character (e.g., ‘_’ or ‘─’)

underline: char

Underline character for emphasis

ellipsis: char

Ellipsis for truncated text (e.g., ‘…’ or ‘…’)

Implementations

impl CharSet

pub fn ascii() -> CharSet

Predefined ASCII character set

pub fn unicode() -> CharSet

Predefined Unicode character set

Trait Implementations

impl Clone for CharSet

fn clone(&self) -> CharSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CharSet

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

Formats the value using the given formatter.

impl Default for CharSet

fn default() -> CharSet

Returns the “default value” for a type.

impl From<*const [*const i8; 23]> for CharSet

fn from(ptr: *const [*const c_char; 23]) -> Self

Converts to this type from the input type.

impl PartialEq for CharSet

fn eq(&self, other: &CharSet) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
