Module jsonrpsee_core::server

Available on crate feature server only.

Shared modules for the JSON-RPC servers.

Re-exports

• pub use helpers::*;

Modules

• helpers
  Helpers.

Structs

• BatchResponse
  Serialized batch response.
• BatchResponseBuilder
  Builder to build a BatchResponse.
• BoundedSubscriptions
  This wraps tokio::sync::Semaphore and is used to limit the number of subscriptions per connection.
• ConnectionId
  Connection ID.
• DisconnectError
  Error that may occur during crate::server::MethodSink::send or crate::server::SubscriptionSink::send.
• Extensions
  A type map of protocol extensions.
• IsUnsubscribed
  Represents a subscription until it is unsubscribed.
• MethodResponse
  Represents a response to a method call.
• MethodResponseFuture
  Future that resolves when the method response has been processed.
• MethodResponseNotifyTx
  Sends a message once the method response has been processed.
• Methods
  Reference-counted, clone-on-write collection of synchronous and asynchronous methods.
• PendingSubscriptionAcceptError
  The error returned while accepting a subscription.
• PendingSubscriptionSink
  Represents a single subscription that is waiting to be accepted or rejected.
• ResponsePayload
  Similar to jsonrpsee_types::ResponsePayload but possible to with an async-like API to detect when a method response has been sent.
• RpcModule
  Sets of JSON-RPC methods can be organized into “module“s that are in turn registered on the server or, alternatively, merged with other modules to construct a cohesive API. RpcModule wraps an additional context argument that can be used to access data during call execution.
• Subscription
  Wrapper struct that maintains a subscription “mainly” for testing.
• SubscriptionKey
  Represent a unique subscription entry based on SubscriptionId and ConnectionId.
• SubscriptionMessage
  Subscription message.
• SubscriptionSink
  Represents a single subscription that hasn’t been processed yet.
• SubscriptionState
  Helper struct to manage subscriptions.

Enums

• CallOrSubscription
  This represent a response to a RPC call and Subscribe calls are handled differently because we want to prevent subscriptions to start before the actual subscription call has been answered.
• MethodCallback
  Callback wrapper that can be either sync or async.
• MethodKind
  The kind of the JSON-RPC method call, it can be a subscription, method call or unknown.
• MethodResponseError
  Method response error.
• MethodResult
  Result of a method, either direct value or a future of one.
• MethodsError
  The error that can occur when Methods::call or Methods::subscribe is invoked.
• NotifyMsg
  A message that that tells whether notification was succesful or not.
• SendTimeoutError
  Error that may occur during crate::server::MethodSink::send_timeout or crate::server::SubscriptionSink::send_timeout.
• SubscriptionCloseResponse
  Represents what action that will sent when a subscription callback returns.
• SubscriptionMessageInner
  A complete subscription message or partial subscription message.
• TrySendError
  Error that may occur during crate::server::MethodSink::try_send or crate::server::SubscriptionSink::try_send.

Traits

• IntoResponse
  Something that can be converted into a JSON-RPC method call response.
• IntoSubscriptionCloseResponse
  Convert something into a subscription close notification before a subscription is terminated.

Functions

• batch_response_error
  Create a JSON-RPC error response.

Type Aliases

• AsyncMethod
  Similar to SyncMethod, but represents an asynchronous handler.
• MaxResponseSize
  Max response size.
• RawRpcResponse
  Raw response from an RPC A tuple containing:
• Subscribers
  Type-alias for subscribers.
• SubscriptionMethod
  Method callback for subscriptions.
• SubscriptionPermit
  Subscription permit.
• SyncMethod
  A MethodCallback is an RPC endpoint, callable with a standard JSON-RPC request, implemented as a function pointer to a Fn function taking four arguments: the id, params, a channel the function uses to communicate the result (or error) back to jsonrpsee, and the connection ID (useful for the websocket transport).
