Struct jsonrpsee::PendingSubscriptionSink

source ·
pub struct PendingSubscriptionSink { /* private fields */ }
Expand description

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§

source§

impl PendingSubscriptionSink

source

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.

§Note

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.

source

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

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

§Panics

Panics if the subscription response exceeded the max_response_size.

source

pub fn connection_id(&self) -> ConnectionId

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

source

pub fn capacity(&self) -> usize

Get the capacity of the channel.

source

pub fn max_capacity(&self) -> usize

Get the max capacity of the channel.

source

pub fn method_name(&self) -> &str

Get the method name.
