Struct FontSize

pub struct FontSize {
    pub numerator: u32,
    pub denominator: u32,
}

A fractional font scaling factor.

Fields

numerator: u32

The numerator of the fractional font scale.

denominator: u32

The denominator of the fractional font scale.

Implementations

impl FontSize

pub const EXTRA_SMALL: Self

An extra-small font size with a value of one-fifth.

pub const SMALL: Self

A small font size with a value of one-fourth.

pub const MEDIUM: Self

A medium font size with a value of one-third.

pub const LARGE: Self

A large font size with a value of one-half.

pub const EXTRA_LARGE: Self

An extra-large font size with a value of two-thirds.

pub const FULL: Self

The full size of the font.

pub const fn new(numerator: u32, denominator: u32) -> Self

Create a custom fractional font size. If you want to create a font size from a floating-point size, use FontSize::from_float instead.

pub fn from_float(size: f32) -> Result<Self, InvalidFontSizeError>

Create a fractional font size from a floating-point size.

Note

This function is lossy, but negligibly so. The highest the denominator can be is 10000.

Errors

• InvalidFontSizeError if the given size is negative.

Trait Implementations

impl Clone for FontSize

fn clone(&self) -> FontSize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FontSize

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

Formats the value using the given formatter.

impl Default for FontSize

fn default() -> Self

Returns the “default value” for a type.

impl From<u32> for FontSize

fn from(value: u32) -> Self

Converts to this type from the input type.

impl PartialEq for FontSize

fn eq(&self, other: &FontSize) -> bool

Tests for self and other values to be equal, and is used by ==.

const 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 TryFrom<f32> for FontSize

type Error = InvalidFontSizeError

The type returned in the event of a conversion error.

fn try_from(value: f32) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<f64> for FontSize

type Error = InvalidFontSizeError

The type returned in the event of a conversion error.

fn try_from(value: f64) -> Result<Self, Self::Error>

Performs the conversion.
