Struct TextScale 

pub struct TextScale {
    pub caption: Option<TextScaleEntry>,
    pub section_heading: Option<TextScaleEntry>,
    pub dialog_title: Option<TextScaleEntry>,
    pub display: Option<TextScaleEntry>,
}

A named text scale with four typographic roles.

Each field is an optional TextScaleEntry so that a partial overlay can override only specific roles.

Fields

caption: Option<TextScaleEntry>

Caption / small label text.

section_heading: Option<TextScaleEntry>

Section heading text.

dialog_title: Option<TextScaleEntry>

Dialog title text.

display: Option<TextScaleEntry>

Large display / hero text.

Implementations

impl TextScale

pub fn merge(&mut self, overlay: &Self)

Merge an overlay into this value. Some fields in the overlay replace the corresponding fields in self; None fields are left unchanged. Nested structs are merged recursively.

pub fn is_empty(&self) -> bool

Returns true if all fields are at their default (None/empty) state.

Trait Implementations

impl Clone for TextScale

fn clone(&self) -> TextScale

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextScale

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

Formats the value using the given formatter.

impl Default for TextScale

fn default() -> TextScale

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TextScale

where TextScale: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TextScale

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

impl Serialize for TextScale

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
