Implementations

impl TextStyle

pub fn new(span_style: SpanStyle, paragraph_style: ParagraphStyle) -> Self

Creates a style from span_style and paragraph_style.

pub fn from_span_style(span_style: SpanStyle) -> Self

Creates a style with span_style and default paragraph settings.

pub fn from_paragraph_style(paragraph_style: ParagraphStyle) -> Self

Creates a style with paragraph_style and default span settings.

pub fn merge(&self, other: &TextStyle) -> TextStyle

Returns a style that merges the span and paragraph styles of other over those of self.

pub fn plus(&self, other: &TextStyle) -> TextStyle

Same as TextStyle::merge. Compose’s TextStyle.plus.

pub fn to_span_style(&self) -> SpanStyle

Returns a copy of the span style.

pub fn to_paragraph_style(&self) -> ParagraphStyle

Returns a copy of the paragraph style.

pub fn platform_style(&self) -> Option<PlatformTextStyle>

Returns the platform-specific settings of the span and the paragraph, or None when neither has any.

pub fn with_platform_style( self, platform_style: Option<PlatformTextStyle>, ) -> Self

Returns this style with the platform-specific settings of the span and the paragraph replaced by those in platform_style.

pub fn resolve_font_size(&self, default_size: f32) -> f32

Returns the font size in sp. See SpanStyle::resolve_font_size.

pub fn resolve_line_height( &self, default_size: f32, natural_line_height: f32, ) -> f32

Returns the line height in the unit of default_size. A positive Sp line height is used as is and a positive Em one multiplies the font size. Otherwise the result is natural_line_height, or the font size when that is not positive and finite.

pub fn resolve_letter_spacing(&self, default_size: f32) -> f32

Returns the letter spacing in the unit of default_size. An Em value multiplies the font size. An unspecified or non-finite spacing gives 0.0.

pub fn resolve_text_color(&self, default_color: Color) -> Color

Returns the text color. See SpanStyle::resolve_foreground_color.

pub fn measurement_hash(&self) -> u64

Hash of the settings that change how the text measures. Colors, decorations and shadows are left out.

pub fn render_hash(&self) -> u64

Hash of every setting that changes how the text looks, as renderers use it to key caches.
