Struct style::values::specified::calc::CalcLengthPercentage

pub struct CalcLengthPercentage {
    pub clamping_mode: AllowedNumericType,
    pub node: CalcNode,
}

A struct to hold a simplified <length> or <percentage> expression.

In some cases, e.g. DOMMatrix, we support calc(), but reject all the relative lengths, and to_computed_pixel_length_without_context() handles this case. Therefore, if you want to add a new field, please make sure this function work properly.

Fields

clamping_mode: AllowedNumericType

node: CalcNode

Implementations

impl CalcLengthPercentage

fn to_computed_value_with_zoom<F>( &self, context: &Context<'_>, zoom_fn: F, base_size: FontBaseSize, line_height_base: LineHeightBase, ) -> LengthPercentage

where F: Fn(Length) -> Length,

Compute the value, zooming any absolute units by the zoom function.

pub fn to_computed_value_zoomed( &self, context: &Context<'_>, base_size: FontBaseSize, line_height_base: LineHeightBase, ) -> LengthPercentage

Compute font-size or line-height taking into account text-zoom if necessary.

pub fn to_computed_pixel_length_without_context(&self) -> Result<CSSFloat, ()>

Compute the value into pixel length as CSSFloat without context, so it returns Err(()) if there is any non-absolute unit.

pub fn to_computed_value(&self, context: &Context<'_>) -> LengthPercentage

Compute the calc using the current font-size and line-height. (and without text-zoom).

fn from_computed_value(computed: &CalcLengthPercentage) -> Self

impl CalcLengthPercentage

fn same_unit_length_as(a: &Self, b: &Self) -> Option<(CSSFloat, CSSFloat)>

Trait Implementations

impl Clone for CalcLengthPercentage

fn clone(&self) -> CalcLengthPercentage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CalcLengthPercentage

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

Formats the value using the given formatter.

impl MallocSizeOf for CalcLengthPercentage

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 PartialEq for CalcLengthPercentage

fn eq(&self, other: &CalcLengthPercentage) -> 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 CalcLengthPercentage

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 ToCss for CalcLengthPercentage

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 CalcLengthPercentage

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

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