Implementations

impl Subscription

pub fn builder() -> SubscriptionBuilder<((), (), (), (), ())>

Create a builder for building Subscription. On the builder, call .symbols(...), .schema(...), .stype_in(...)(optional), .start(...)(optional), .use_snapshot(...)(optional) to set the values of the fields. Finally, call .build() to create the instance of Subscription.

Trait Implementations

impl Clone for Subscription

fn clone(&self) -> Subscription

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Subscription

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

Formats the value using the given formatter.

impl PartialEq for Subscription

fn eq(&self, other: &Subscription) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
