Enum TextScaling 

pub enum TextScaling {
    Renderer,
    Resolved,
    Content,
}

What a TextStyle’s size (and pixel letter spacing) is measured in.

Text must be scaled exactly once. A theme role is already resolved; a renderer-relative base size is scaled by the renderer; a document’s own type is never scaled by an accessibility preference at all.

Variants

Renderer

A 1× base size. The renderer multiplies it by its accessibility text scale. TextStyle::new and the size-based renderer APIs use this.

Resolved

A final logical size that already includes the theme’s UI and text scale: every crate::theme::Theme::text role. Painted as given.

Content

A document-space size that belongs to the content, not the chrome: a zoomed canvas, a PDF stamp, a terminal grid. Painted as given and never grown by the text scale; the content’s own zoom scales it.

Trait Implementations

impl Clone for TextScaling

fn clone(&self) -> TextScaling

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextScaling

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

Formats the value using the given formatter.

impl Default for TextScaling

fn default() -> TextScaling

Returns the “default value” for a type.

impl Hash for TextScaling

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TextScaling

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