Struct LineHeight 

pub struct LineHeight(/* private fields */);

A custom type to ensure the minimum number of lines is a positive, non-zero f32.

Implementations

impl LineHeight

pub fn new(height: f32) -> Option<LineHeight>

Creates a line-height ratio where height is not equal to zero.

pub fn get(&self) -> f32

Returns the validated line-height ratio.

pub fn deserialize<'de, D>( deserializer: D, ) -> Result<LineHeight, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserializes a non-zero line-height ratio.

Trait Implementations

impl Clone for LineHeight

fn clone(&self) -> LineHeight

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LineHeight

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

Formats the value using the given formatter.

impl Default for LineHeight

fn default() -> LineHeight

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LineHeight

fn deserialize<__D>( __deserializer: __D, ) -> Result<LineHeight, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LineHeight

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

impl Serialize for LineHeight

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for LineHeight

impl StructuralPartialEq for LineHeight
