Trait Implementations

impl Clone for TextStyle

fn clone(&self) -> TextStyle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextStyle

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

Formats the value using the given formatter.

impl Default for TextStyle

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for TextStyle

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