Trait Implementations

impl Clone for ScrollCmd

fn clone(&self) -> ScrollCmd

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollCmd

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ScrollCmd

fn deserialize<__D>( __deserializer: __D, ) -> Result<ScrollCmd, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl IntoVar<Option<ScrollCmd>> for ScrollCmd

type Var = LocalVar<Option<ScrollCmd>>

Variable type that will wrap the T value.

fn into_var(self) -> <ScrollCmd as IntoVar<Option<ScrollCmd>>>::Var

Converts the source value into a var.

fn into_boxed_var(self) -> Box<dyn VarBoxed<T>>

where Self: Sized,

Converts into BoxedVar<T>.

impl PartialEq for ScrollCmd

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