Struct Theme 

pub struct Theme {
    pub bar_filled: char,
    pub bar_empty: char,
    pub spinner_frames: &'static [char],
}

A theme for customizing the appearance of the TerminalFrontend.

This struct dictates the characters used to paint the progress indicators. It provides defaults suitable for modern terminals supporting UTF-8.

Fields

bar_filled: char

The character used for the filled portion of a progress bar (e.g., ‘█’).

bar_empty: char

The character used for the empty portion of a progress bar (e.g., ‘░’).

spinner_frames: &'static [char]

The sequence of characters used to animate spinner frames.

Implementations

impl Theme

pub const fn ascii() -> Self

A simple ASCII-only theme for environments with limited character support.

Use this in CI environments, basic command prompts, or when UTF-8 support cannot be guaranteed.

pub const fn modern() -> Self

Provides a modern, UTF-8 based default theme.

This theme uses block characters for bars and braille patterns for spinners, offering a visually rich experience in compatible terminals.

Trait Implementations

impl Clone for Theme

fn clone(&self) -> Theme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Theme

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

Formats the value using the given formatter.

impl Default for Theme

fn default() -> Self

Provides a modern, UTF-8 based default theme.

impl PartialEq for Theme

fn eq(&self, other: &Theme) -> 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.
