Struct OptionFont 

pub struct OptionFont<'a> {
    pub font: Option<UiFont<'a>>,
}

Wrapper for optional font values with style fallback.

This struct provides a convenient way to handle optional font parameters in widgets. When a font is not explicitly set, it falls back to the default font from the global style configuration.

Type Parameters

• 'a - The lifetime of the font reference

Example

use matrix_gui::prelude::*;

// Create with no font set
let mut font = OptionFont::none();

// Get font with fallback to style
let actual_font = font.font(&style);

Fields

font: Option<UiFont<'a>>

The optional font value.

Implementations

impl<'a> OptionFont<'a>

pub const fn none() -> Self

Creates a new OptionFont with no font set.

Returns

A new OptionFont instance with font set to None.

pub const fn set_font(&mut self, font: UiFont<'a>)

Sets the font value.

Arguments

• font - The font to set.

pub fn font<COL: PixelColor>(&self, style: &Style<COL>) -> UiFont<'a>

Returns the font, falling back to the style default if not set.

Type Parameters

Arguments

• style - Reference to the style configuration.

Returns

The set font if present, otherwise style.default_font.
