Enum MethodCallback 

pub enum MethodCallback {
    Sync(Arc<dyn Fn(Id<'_>, Params<'_>, usize) -> MethodResponse + Sync + Send>),
    Async(Arc<dyn Fn(Id<'static>, Params<'static>, ConnectionId, usize) -> Pin<Box<dyn Future<Output = MethodResponse> + Send>> + Sync + Send>),
    Subscription(Arc<dyn Fn(Id<'_>, Params<'_>, MethodSink, SubscriptionState<'_>) -> Pin<Box<dyn Future<Output = MethodResponse> + Send>> + Sync + Send>),
    Unsubscription(Arc<dyn Fn(Id<'_>, Params<'_>, ConnectionId, usize) -> MethodResponse + Sync + Send>),
}

Available on crate feature server-core only.

Callback wrapper that can be either sync or async.

Variants

Sync(Arc<dyn Fn(Id<'_>, Params<'_>, usize) -> MethodResponse + Sync + Send>)

Trait Implementations

impl Clone for MethodCallback

fn clone(&self) -> MethodCallback

Returns a duplicate of the value.

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
