Implementations

impl Resolution

pub fn from_dppx(value: CSSFloat) -> Self

Returns a resolution value from dppx units.

pub fn from_x(value: CSSFloat) -> Self

Returns a resolution value from dppx units.

pub fn from_dppx_calc(value: CSSFloat) -> Self

Returns a resolution value from dppx units.

pub fn dppx(&self) -> CSSFloat

Convert this resolution value to dppx units.

pub fn dpi(&self) -> CSSFloat

Convert this resolution value to dpi units.

pub fn parse_dimension<'i, 't>(value: CSSFloat, unit: &str) -> Result<Self, ()>

Parse a resolution given a value and unit.

Trait Implementations

impl Clone for Resolution

fn clone(&self) -> Resolution

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Resolution

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

Formats the value using the given formatter.

impl MallocSizeOf for Resolution

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 Resolution

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

Parse a value of this type.

impl PartialEq for Resolution

fn eq(&self, other: &Resolution) -> bool

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SpecifiedValueInfo for Resolution

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 Resolution

type ComputedValue = Resolution

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 Resolution

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 Resolution

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

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