Enum FontSize 

pub enum FontSize {
    Pt(f32),
    Px(f32),
}

A font size with an explicit unit.

In TOML presets, this appears as either size_pt (typographic points) or size_px (logical pixels). That mapping is done by the parent structs (FontSpec, TextScaleEntry); FontSize derives Serialize and Deserialize of its own for ResolvedFontSpec::defined_size.

During validation, all FontSize values are converted to logical pixels via FontSize::to_logical_px(dpi), producing a plain f32 for the resolved model.

Variants

Pt(f32)

Typographic points (1/72 inch). Stated by the OS readers (KDE, GNOME, macOS, Windows) and by the platform presets other than Material (Adwaita, KDE Breeze, macOS, Windows 11, iOS). Converted to px during validation: px = pt * dpi / 72.

Px(f32)

Logical pixels. Stated by the Material platform preset and the community colour-scheme presets (Catppuccin, Dracula, Gruvbox, Nord, One Dark, Solarized, Tokyo Night).

Implementations

impl FontSize

pub fn to_logical_px(self, dpi: f32) -> f32

Convert to logical pixels.

• Pt(v) -> v * dpi / 72.0 (DPI matters)
• Px(v) -> v (already logical pixels, DPI ignored)

The name to_logical_px makes the asymmetry explicit: Px values are already in logical pixels, so the DPI parameter has no effect.

Examples

use native_theme::theme::FontSize;

// Pt branch: DPI affects the result
let pt_size = FontSize::Pt(10.0);
assert_eq!(pt_size.to_logical_px(96.0), 10.0 * 96.0 / 72.0);
assert_eq!(pt_size.to_logical_px(72.0), 10.0); // identity at 72 DPI

// Px branch: DPI is ignored, value returned unchanged
let px_size = FontSize::Px(14.0);
assert_eq!(px_size.to_logical_px(96.0), 14.0);
assert_eq!(px_size.to_logical_px(144.0), 14.0); // same regardless of DPI

pub fn raw(self) -> f32

Return the raw numeric value regardless of unit. Used during inheritance to compute derived values (e.g. line_height) before unit conversion.

pub fn is_pt(self) -> bool

True when the value is in typographic points.
