Enum ScrollMethod

#[non_exhaustive]
pub enum ScrollMethod {
    NoScroll,
    TwoFinger,
    Edge,
    OnButtonDown,
}

The scroll method of a device selects when to generate scroll axis events instead of pointer motion events.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoScroll

Never send scroll events instead of pointer motion events.

This has no effect on events generated by scroll wheels.

TwoFinger

Send scroll events when two fingers are logically down on the device.

Edge

Send scroll events when a finger moves along the bottom or right edge of a device.

OnButtonDown

Send scroll events when a button is down and the device moves along a scroll-capable axis.

Trait Implementations

impl Clone for ScrollMethod

fn clone(&self) -> ScrollMethod

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollMethod

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

Formats the value using the given formatter.

impl Hash for ScrollMethod

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ScrollMethod

fn eq(&self, other: &ScrollMethod) -> 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.
