Struct RingMark 

pub struct RingMark {
    pub color: Option<Color>,
    pub rx: Option<f32>,
    pub ry: Option<f32>,
    pub width: Option<f32>,
    pub each: bool,
}

圈注参数。半径给定后圈的大小与文字宽窄无关——日历里「1」和「10」能圈出同样大的圈。

Fields

color: Option<Color>

描边颜色;None = 跟随文字墨色。

rx: Option<f32>

横向半径(逻辑像素);None = 按文字宽自适应。

ry: Option<f32>

纵向半径(逻辑像素);None 且 rx 有值 = 取 rx(正圆),都缺 = 按字高自适应。

width: Option<f32>

线宽(逻辑像素);None = 0.07 倍字号。

each: bool

逐字圈:整段一字一圈(空白跳过),全自适应时缺省正圆;false = 整段一个圈 (范围圈,自适应为扁椭圆)。

Trait Implementations

impl Clone for RingMark

fn clone(&self) -> RingMark

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RingMark

impl Debug for RingMark

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

Formats the value using the given formatter.

impl Default for RingMark

fn default() -> RingMark

Returns the “default value” for a type.

impl PartialEq for RingMark

fn eq(&self, other: &RingMark) -> 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.
