Struct PiecewiseLinearFunction 

#[repr(C)]
pub struct PiecewiseLinearFunction {
    entries: ArcSlice<PiecewiseLinearFunctionEntry>,
}

Representation of a piecewise linear function, a series of linear functions.

Fields

entries: ArcSlice<PiecewiseLinearFunctionEntry>

Implementations

impl PiecewiseLinearFunction

fn interpolate( x: CSSFloat, prev: PiecewiseLinearFunctionEntry, next: PiecewiseLinearFunctionEntry, asymptote: &PiecewiseLinearFunctionEntry, ) -> CSSFloat

Interpolate y value given x and two points. The linear function will be rooted at the asymptote.

pub fn at(&self, x: CSSFloat) -> CSSFloat

Get the y value of the piecewise linear function given the x value, as per https://drafts.csswg.org/css-easing-2/#linear-easing-function-output

pub fn iter(&self) -> Iter<'_, PiecewiseLinearFunctionEntry>

Trait Implementations

impl Clone for PiecewiseLinearFunction

fn clone(&self) -> PiecewiseLinearFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PiecewiseLinearFunction

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

Formats the value using the given formatter.

impl Default for PiecewiseLinearFunction

fn default() -> PiecewiseLinearFunction

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PiecewiseLinearFunction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl MallocSizeOf for PiecewiseLinearFunction

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 PiecewiseLinearFunction

fn eq(&self, other: &PiecewiseLinearFunction) -> 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 Serialize for PiecewiseLinearFunction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl SpecifiedValueInfo for PiecewiseLinearFunction

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 PiecewiseLinearFunction

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.

fn to_css_cssstring(&self) -> String

Serialize self in CSS syntax and return a CssString.

impl ToResolvedValue for PiecewiseLinearFunction

where ArcSlice<PiecewiseLinearFunctionEntry>: ToResolvedValue<ResolvedValue = ArcSlice<PiecewiseLinearFunctionEntry>>,

type ResolvedValue = PiecewiseLinearFunction

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

fn from_resolved_value(from: Self::ResolvedValue) -> Self

Convert a resolved value to resolved value form.

fn to_resolved_value(self, context: &Context<'_>) -> Self::ResolvedValue

Convert a resolved value to a resolved value.

impl ToShmem for PiecewiseLinearFunction

where ArcSlice<PiecewiseLinearFunctionEntry>: ToShmem,

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

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