Enum Autoscroll 

#[non_exhaustive]
#[repr(u32)]
pub enum Autoscroll {
    None = 0,
    Up = 1,
    Down = 2,
}

Current autoscroll direction for an active selection drag gesture.

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.

None = 0

No selection autoscroll is requested.

Up = 1

Selection dragging should autoscroll the viewport upward.

Down = 2

Selection dragging should autoscroll the viewport downward.

Trait Implementations

impl Clone for Autoscroll

fn clone(&self) -> Autoscroll

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Autoscroll

impl Debug for Autoscroll

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

Formats the value using the given formatter.

impl Eq for Autoscroll

impl From<Autoscroll> for u32

fn from(v: Autoscroll) -> Self

Converts to this type from the input type.

impl PartialEq for Autoscroll

fn eq(&self, other: &Autoscroll) -> 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 StructuralPartialEq for Autoscroll

impl TryFrom<u32> for Autoscroll

type Error = u32

The type returned in the event of a conversion error.

fn try_from(v: u32) -> Result<Self, u32>

Performs the conversion.
