Struct jsonrpsee_server::PendingSubscriptionSink

pub struct PendingSubscriptionSink { /* private fields */ }

Represents a single subscription that is waiting to be accepted or rejected.

If this is dropped without calling PendingSubscription::reject or PendingSubscriptionSink::accept a default error is sent out as response to the subscription call.

Thus, if you want a customized error message then PendingSubscription::reject must be called.

Implementations

impl PendingSubscriptionSink

pub async fn reject(self, err: impl Into<ErrorObject<'static>>)

Reject the subscription by responding to the subscription method call with the error message from jsonrpsee_types::error::ErrorObject.

If this is used in the async subscription callback the return value is simply ignored because no further notification are propagated once reject has been called.

pub async fn accept( self, ) -> Result<SubscriptionSink, PendingSubscriptionAcceptError>

Attempt to accept the subscription and respond the subscription method call.

Panics if the subscription response exceeded the max_response_size.

pub fn connection_id(&self) -> ConnectionId

Returns connection identifier, which was used to perform pending subscription request

pub fn capacity(&self) -> usize

Get the capacity of the channel.

pub fn max_capacity(&self) -> usize
