Enum style::values::specified::box_::Zoom

pub enum Zoom {
    Normal,
    Document,
    Value(NonNegativeNumberOrPercentage),
}

A specified value for the zoom property.

Variants

Normal

Document

An internal value that resets the effective zoom to 1. Used for scrollbar parts, which disregard zoom. We use this name because WebKit has this value exposed to the web.

Value(NonNegativeNumberOrPercentage)

Implementations

impl Zoom

pub fn new_number(n: f32) -> Self

Return a particular number value of the zoom property.

Trait Implementations

impl Clone for Zoom

fn clone(&self) -> Zoom

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Zoom

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

Formats the value using the given formatter.

impl MallocSizeOf for Zoom

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 Parse for Zoom

fn parse<'i, 't>( context: &ParserContext<'_>, input: &mut Parser<'i, 't>, ) -> Result<Self, ParseError<'i>>

Parse a value of this type.

impl PartialEq for Zoom

fn eq(&self, other: &Zoom) -> 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 SpecifiedValueInfo for Zoom

const SUPPORTED_TYPES: u8 = 0u8

Supported CssTypes by the given value type.

fn collect_completion_keywords(_f: &mut dyn FnMut(&[&'static str]))

Collect value starting words for the given specified value type. This includes keyword and function names which can appear at the beginning of a value of this type.

impl ToComputedValue for Zoom

type ComputedValue = Zoom

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

fn to_computed_value(&self, _: &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 ToCss for Zoom

fn to_css<W>(&self, dest: &mut CssWriter<'_, 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.

impl ToShmem for Zoom

fn to_shmem(&self, builder: &mut SharedMemoryBuilder) -> Result<Self>

Clones this value into a form suitable for writing into a SharedMemoryBuilder.

impl Copy for Zoom

impl StructuralPartialEq for Zoom
