Implementations

impl Length

pub fn resolve_to_f32<L: LengthNum>( &self, media_query_status: &MediaQueryStatus<L>, relative_length: f32, length_as_parent_font_size: bool, ) -> Option<f32>

Resolve the length value to f32.

The relative_length is used to calculate ...% length. If length_as_parent_font_size is set, the relative_length is used for em length; otherwise the base font size in media_query_status is used.

pub fn resolve_length<L: LengthNum>( &self, media_query_status: &MediaQueryStatus<L>, relative_length: L, ) -> Option<L>

Resolve the length value to L.

The relative_length is used to calculate ...% length. The base font size in media_query_status is used for em length.

impl Length

pub fn to_f32(&self) -> f32

Erase the unit and leave the f32 value.

Panics if it is an expression or it does not contain a unit.

Trait Implementations

impl Clone for Length

fn clone(&self) -> Length

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Length

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

Formats the value using the given formatter.

impl Default for Length

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Length

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Length

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

Formats the value using the given formatter.

impl From<Length> for LengthType

fn from(x: Length) -> LengthType

Converts to this type from the input type.

impl PartialEq for Length

fn eq(&self, other: &Length) -> 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 Length

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
