Struct Palette 

#[non_exhaustive]
pub struct Palette {

    pub fg: Color,
    pub fg_dim: Color,
    pub bg: Color,
    pub surface: Color,
    pub overlay: Color,
    pub accent: Color,
    pub on_accent: Color,
    pub selection: Color,
    pub border: Color,

语义色板——主题系统的唯一颜色真源。

每个内置组件的 FooTheme::from_palette 只从这里取色;改这一处即可统一全部组件观感。 标注 #[non_exhaustive]:后续新增语义色不构成对下游的破坏性变更。下游经 Palette::default + 字段修改构造,而非结构体字面量。

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.

fg: Color

主前景色(正文文字)。

fg_dim: Color

弱化前景(次要文字、禁用态)。

bg: Color

主背景色。

surface: Color

面板/容器表面色(比 bg 略微抬升的层)。

overlay: Color

遮罩层底色(模态背景)。

accent: Color

强调色(高亮、激活边框、选中背景)。

on_accent: Color

强调底色其上的前景(如高亮行的文字色,与 accent/selection 配对)。

selection: Color

选中项背景。

border: Color

常态边框色。

border_active: Color

激活/聚焦边框色。

success: Color

成功语义色。

warning: Color

警告语义色。

error: Color

错误语义色。

info: Color

信息语义色。

placeholder: Color

占位符/提示文字色。

Trait Implementations

impl Clone for Palette

fn clone(&self) -> Palette

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Palette

impl Debug for Palette

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Palette

fn default() -> Self

一套自洽的默认配色:交互/高亮走 accent(cyan)族,边框常态 dim、激活 accent, 语义色 success/warning/error/info = green/yellow/red/blue,前景/背景默认跟随终端(Reset)。

impl Eq for Palette

impl PartialEq for Palette

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
