Enum style::values::specified::image::LineDirection

pub enum LineDirection {
    Angle(Angle),
    Horizontal(HorizontalPositionKeyword),
    Vertical(VerticalPositionKeyword),
    Corner(HorizontalPositionKeyword, VerticalPositionKeyword),
}

A specified gradient line direction.

FIXME(emilio): This should be generic over Angle.

Variants

Angle(Angle)

An angular direction.

Horizontal(HorizontalPositionKeyword)

A horizontal direction.

Vertical(VerticalPositionKeyword)

A vertical direction.

Corner(HorizontalPositionKeyword, VerticalPositionKeyword)

A direction towards a corner of a box.

Implementations

impl LineDirection

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

Trait Implementations

impl Clone for LineDirection

fn clone(&self) -> LineDirection

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LineDirection

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

Formats the value using the given formatter.

impl LineDirection for LineDirection

fn points_downwards(&self, compat_mode: GradientCompatMode) -> bool

Whether this direction points towards, and thus can be omitted.

fn to_css<W>( &self, dest: &mut CssWriter<'_, W>, compat_mode: GradientCompatMode, ) -> Result

where W: Write,

Serialises this direction according to the compatibility mode.

impl MallocSizeOf for LineDirection

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 LineDirection

fn eq(&self, other: &LineDirection) -> 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 ToComputedValue for LineDirection

type ComputedValue = LineDirection

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 ToShmem for LineDirection

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

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