Implementations

impl RelativeFontSize

pub fn parse(s: &str) -> Option<Self>

Parse a string into a RelativeFontSize

pub fn resolve(&self, parent_size: Length) -> Length

Resolve to an absolute font size

For larger/smaller, requires parent font size For absolute keywords, ignores parent and returns fixed size

pub fn is_relative(&self) -> bool

Check if this is a relative size (larger/smaller)

pub fn is_absolute_keyword(&self) -> bool

Check if this is an absolute keyword size

Trait Implementations

impl Clone for RelativeFontSize

fn clone(&self) -> RelativeFontSize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelativeFontSize

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

Formats the value using the given formatter.

impl PartialEq for RelativeFontSize

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