Enum TimelineRangeName 

#[repr(u8)]
pub enum TimelineRangeName {
    None = 0,
    Cover = 1,
    Contain = 2,
    Entry = 3,
    Exit = 4,
    EntryCrossing = 5,
    ExitCrossing = 6,
    Scroll = 7,
}

The value type, which indicates a CSS identifier representing one of the predefined named timeline ranges. https://drafts.csswg.org/scroll-animations-1/#named-ranges

For now, only view timeline ranges use this type. https://drafts.csswg.org/scroll-animations-1/#view-timelines-ranges

Variants

None = 0

The default value. No timeline range name specified.

Cover = 1

Represents the full range of the view progress timeline

Contain = 2

Represents the range during which the principal box is either fully contained by, or fully covers, its view progress visibility range within the scrollport.

Entry = 3

Represents the range during which the principal box is entering the view progress visibility range.

Exit = 4

Represents the range during which the principal box is exiting the view progress visibility range.

EntryCrossing = 5

Represents the range during which the principal box crosses the end border edge.

ExitCrossing = 6

Represents the range during which the principal box crosses the start border edge.

Scroll = 7

Represents the full range of the scroll container on which the view progress timeline is defined.

Implementations

Trait Implementations

impl Clone for TimelineRangeName

fn clone(&self) -> TimelineRangeName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimelineRangeName

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

Formats the value using the given formatter.

impl MallocSizeOf for TimelineRangeName

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

impl Parse for TimelineRangeName

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

Parse a value of this type.

impl PartialEq for TimelineRangeName

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

Tests for self and other values to be equal, and is used by ==.
