Implementations

impl Carousel

pub fn builder() -> CarouselBuilder

constract CarouselBuilder object.

Trait Implementations

impl Clone for Carousel

fn clone(&self) -> Carousel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Carousel

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

Formats the value using the given formatter.

impl From<Carousel> for Block

fn from(value: Carousel) -> Self

Converts to this type from the input type.

impl PartialEq for Carousel

fn eq(&self, other: &Carousel) -> 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 Serialize for Carousel

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Carousel
