Enum NaturalScroll 

#[repr(C)]
pub enum NaturalScroll {
    Disabled = 0,
    Enabled = 1,
    System = 2,
}

How the engine treats scroll direction (9b-ii-b-i-a) - see AppConfig::natural_scroll.

Variants

Disabled = 0

Never flip a delta in the engine. The OS’s own preference, if the user set one, still reaches the app in the deltas.

Enabled = 1

Flip every wheel and trackpad delta in the engine.

System = 2

Read the platform’s preference at startup and keep it readable; no engine flip, since the platform already applied it to the deltas.

impl Ord for NaturalScroll

fn cmp(&self, other: &NaturalScroll) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for NaturalScroll

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for NaturalScroll

fn partial_cmp(&self, other: &NaturalScroll) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
