Trait Implementations

impl ApiKey for DeleteTopicsService

const KEY: i16 = DeleteTopicsRequest::KEY

impl Clone for DeleteTopicsService

fn clone(&self) -> DeleteTopicsService

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeleteTopicsService

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

impl Default for DeleteTopicsService

fn default() -> DeleteTopicsService

Returns the “default value” for a type.

impl Hash for DeleteTopicsService

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 Ord for DeleteTopicsService

fn cmp(&self, other: &DeleteTopicsService) -> 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.

impl PartialEq for DeleteTopicsService

fn eq(&self, other: &DeleteTopicsService) -> 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 PartialOrd for DeleteTopicsService

fn partial_cmp(&self, other: &DeleteTopicsService) -> 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

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

impl<G> Service<G, DeleteTopicsRequest> for DeleteTopicsService

where G: Storage,

type Response = DeleteTopicsResponse

The type of response returned by the service.

type Error = Error

The type of error returned by the service.

async fn serve( &self, ctx: Context<G>, req: DeleteTopicsRequest, ) -> Result<Self::Response, Self::Error>

Serve a response or error for the given request, using the given context.

fn boxed(self) -> BoxService<S, Request, Self::Response, Self::Error>

Box this service to allow for dynamic dispatch.
