Enum Dimension 

pub enum Dimension<T> {
    Undefined,
    Auto,
    Points(T),
    Percentage(T),
}

Represents an absolute or relative dimension.

Variants

Undefined

This is the default value for a dimension and resembles Dimension:::Points(0.0) and Dimension::Percentage(0.0).

Auto

Depending on the property that this dimension is used to, this value may have a special meaning. Otherwise, it’s similar to Dimension::Undefined.

Points(T)

This is a dimension expressed in absolute units, where each unit represents a single pixel.

Percentage(T)

This is a dimension expressed in relative units, where 1.0 represents 100%.

Trait Implementations

impl<T: Clone> Clone for Dimension<T>

fn clone(&self) -> Dimension<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Dimension<T>

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

Formats the value using the given formatter.

impl<T> Default for Dimension<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> FromStr for Dimension<T>

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Dimension<T>, Self::Err>

Parses a string s to return a value of this type.

impl<T: PartialEq> PartialEq for Dimension<T>

fn eq(&self, other: &Dimension<T>) -> 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<T: Copy> Copy for Dimension<T>

impl<T: Eq> Eq for Dimension<T>
