Struct Theme 

#[non_exhaustive]
pub struct Theme {
    pub bg_color: String,
    pub default_font: String,
    pub text_mode: TextMode,
    pub ink: Option<String>,
    pub panel_bg: Option<String>,
    pub panel_border: Option<String>,
    pub cursor_color: Option<String>,
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

bg_color: String

default_font: String

text_mode: TextMode

How text is positioned. Tile (default) keeps the legacy Game Boy 8×8 per-glyph grid; Proportional renders at pixel precision with per-glyph advance (for high-resolution, CJK-correct screens). The proportional path also requires Painter::supports_proportional() — both must hold, so any layout without an explicit theme (e.g. all pokered screens) stays on Tile.

ink: Option<String>

Default ink colour for text/list/cursor when no element-level color is set. None → the legacy INK_BLACK.

panel_bg: Option<String>

Panel interior fill (for game-themed boxes drawn via pixel_rect).

panel_border: Option<String>

Panel border colour.

cursor_color: Option<String>

Cursor (▶) colour; None → the resolved ink.

Implementations

impl Theme

pub fn ink_color(&self) -> Rgba

Resolve the ink colour: theme.ink if set, else the legacy INK_BLACK.

pub fn cursor_ink(&self) -> Rgba

Resolve the cursor colour: theme.cursor_color, else ink, else INK_BLACK.

pub fn proportional(&self, painter_supports: bool) -> bool

Whether to use the proportional path given the painter’s capability.

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

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Theme

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
