Get the direction as a lowercase string.

Trait Implementations

impl Clone for ScrollDirection

fn clone(&self) -> ScrollDirection

Returns a duplicate of the value.

Performs copy-assignment from source.

impl Debug for ScrollDirection

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

Formats the value using the given formatter.

impl Display for ScrollDirection

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

impl FromStr for ScrollDirection

type Err = ScrollDirectionError

The associated error which can be returned from parsing.
