Trait Implementations

impl Clone for ScrollDirection

fn clone(&self) -> ScrollDirection

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollDirection

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

Formats the value using the given formatter.

impl Default for ScrollDirection

fn default() -> ScrollDirection

Returns the “default value” for a type.

impl Display for ScrollDirection

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

Formats the value using the given formatter.

impl FromStr for ScrollDirection

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<ScrollDirection, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for ScrollDirection

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 ScrollDirection

fn eq(&self, other: &ScrollDirection) -> 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 TryFrom<&str> for ScrollDirection

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<ScrollDirection, <Self as TryFrom<&str>>::Error>

Performs the conversion.
