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 for Dimension<T>

where T: Clone,

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 for Dimension<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for Dimension<T>

fn default() -> Dimension<T>

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>, <Dimension<T> as FromStr>::Err>

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

impl<S> Parse<S> for Dimension<f32>

where S: TokenStream,

type Output = Dimension<f32>

The type that is parsed.

fn parse<'a>( tokens: &'a [TokenTree<S>], ) -> (Option<<Dimension<f32> as Parse<S>>::Output>, &'a [TokenTree<S>])

This function should return an instance of the type if it can be parsed, or None otherwise, and a slice of tokens that remain after parsing if successful (or the original slice otherwise).

impl<T> PartialEq for Dimension<T>

where T: PartialEq,

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> ToTokens for Dimension<T>

where T: ToTokens,

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.

impl<T> Copy for Dimension<T>

where T: Copy,

impl<T> Eq for Dimension<T>

where T: Eq,

impl<T> StructuralPartialEq for Dimension<T>
