Struct Theme 

pub struct Theme {
    pub colors: Colors,
    pub lines: Graphics,
    pub align_to_values: bool,
}

A complete theme for tree display.

A theme combines color configuration and line graphics to define the visual appearance of tree output. Themes control everything from syntax highlighting colors to the characters used for drawing tree lines.

Example

use tree_display::{Theme, Colors, Graphics};

// Use the default theme
let theme = Theme::default();

// Create a custom theme
let custom = Theme::new()
    .colors(Colors::VSCODE_DARK_PLUS)
    .lines(Graphics::LIGHT_ROUNDED)
    .align_to_values(true);

Fields

colors: Colors

Color configuration for syntax highlighting

lines: Graphics

Line characters for tree drawing

align_to_values: bool

Whether to align labels with values vertically

When true: subtrees are aligned with the values they describe.

When false: all subtrees have the same consistent indentation.

Implementations

impl Theme

pub const fn new() -> Self

Creates a new Theme with default settings.

The default theme uses no colors, light Unicode lines, and no value alignment.

pub const fn colors(self, colors: Colors) -> Self

Sets the color configuration for this theme.

pub const fn lines(self, lines: Graphics) -> Self

Sets the line graphics for this theme.

pub const fn align_to_values(self, align_to_values: bool) -> Self

Sets whether subtrees should be aligned with values.

When true: subtrees are aligned with the values they describe.

When false: all subtrees have the same consistent indentation.

Trait Implementations

impl Clone for Theme

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Theme

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

Creates a new Theme with default settings.

The default theme uses no colors, light Unicode lines, and no value alignment.

impl Eq for Theme

impl Ord for Theme

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Theme

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Theme

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
