Struct Formatter 

pub struct Formatter<'value, 'context, T: TreeDisplay> { /* private fields */ }

Configurable formatter for tree display.

A formatter holds a value that implements TreeDisplay along with optional theme and context settings. It produces a formatted string representation of the tree.

Example

use tree_display::{Formatter, Theme};

let value = 0;
let output = Formatter::of(&value)
    .theme(Theme::default())
    .format();

Implementations

impl<'value, 'context, T: TreeDisplay> Formatter<'value, 'context, T>

pub fn of(value: &'value T) -> Self

Creates a new formatter for the given value.

pub fn theme(&mut self, theme: Theme) -> &mut Self

Sets the theme for this formatter.

pub fn context(&mut self, context: &'context Context) -> &mut Self

The context provides custom mappers for transforming values during tree display.
