Struct style::values::generics::NonNegative

pub struct NonNegative<T>(pub T);

A wrapper of Non-negative values.

Trait Implementations

impl<T> Animate for NonNegative<T> where
    T: Animate, 

fn animate(&self, other: &Self, procedure: Procedure) -> Result<Self, ()>

Animate a value towards another one, given an animation procedure.

impl<T: Clone> Clone for NonNegative<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> ComputeSquaredDistance for NonNegative<T> where
    T: ComputeSquaredDistance, 

fn compute_squared_distance(&self, other: &Self) -> Result<SquaredDistance, ()>

Computes the squared distance between two animatable values.

impl<T: Copy> Copy for NonNegative<T>

impl<T: Debug> Debug for NonNegative<T>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<T> MallocSizeOf for NonNegative<T> where
    T: MallocSizeOf, 

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl<T: PartialEq> PartialEq for NonNegative<T>

fn eq(&self, __arg_0: &NonNegative<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &NonNegative<T>) -> bool

This method tests for !=.

impl<T: PartialOrd> PartialOrd for NonNegative<T>

fn partial_cmp(&self, __arg_0: &NonNegative<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &NonNegative<T>) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &NonNegative<T>) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &NonNegative<T>) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &NonNegative<T>) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<T> ToAnimatedZero for NonNegative<T> where
    T: ToAnimatedZero, 

fn to_animated_zero(&self) -> Result<Self, ()>

Returns a value that, when added with an underlying value, will produce the underlying value. This is used for SMIL animation's "by-animation" where SMIL first interpolates from the zero value to the 'by' value, and then adds the result to the underlying value.

impl<T> ToComputedValue for NonNegative<T> where
    T: ToComputedValue, 

type ComputedValue = NonNegative<<T as ToComputedValue>::ComputedValue>

The computed value type we're going to be converted to.

fn to_computed_value(&self, context: &Context) -> Self::ComputedValue

Convert a specified value to a computed value, using itself and the data inside the Context.

fn from_computed_value(computed: &Self::ComputedValue) -> Self

Convert a computed value to specified value form.

impl<T> ToCss for NonNegative<T> where
    T: ToCss, 

fn to_css<W>(&self, dest: &mut W) -> Result where
    W: Write, 

Serialize self in CSS syntax, writing to dest.

fn to_css_string(&self) -> String

Serialize self in CSS syntax and return a string.
