Enum TouchAction 

pub enum TouchAction {
    Auto,
    PanX,
    PanY,
    None,
}

A simplified representation of the CSS touch-action property, used by the compositor to decide how a touch gesture may scroll a given node.

NOTE: Directional variants (pan-left/pan-right/…) are not supported in Stylo at all. Firefox also fails the parsing.

Variants

Auto

touch-action: auto (and manipulation, pan-x pan-y). The compositor applies the scroll-chaining axis lock: lock to the dominant axis only when the hit node cannot scroll that axis.

PanX

touch-action: pan-x. The vertical axis is excluded from input-event scrolling (chains to ancestor); the gesture locks to its dominant axis.

PanY

touch-action: pan-y. The horizontal axis is excluded from input-event scrolling (chains to ancestor); the gesture locks to its dominant axis.

None

touch-action: none (and pinch-zoom alone). No single-finger direct manipulation: do not scroll.

Trait Implementations

impl Clone for TouchAction

fn clone(&self) -> TouchAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TouchAction

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TouchAction

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<TouchAction> for TouchAction

fn from(stylo: TouchAction) -> Self

Converts to this type from the input type.

impl MallocSizeOf for TouchAction

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 TouchAction

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TouchAction
