Structs

ArcSchema

This exists as a work-around for this issue: https://github.com/rust-lang/rust/issues/64552

Connection

Implements the graphql-ws protocol. This is a sink for TryInto<Input> messages and a stream of Output messages.

ConnectionConfig

ConnectionConfig is used to configure the connection once the client sends the ConnectionInit message.

ErrorPayload

A payload for errors that can happen before execution. Errors that happen during execution are instead sent to the client via NextPayload. ErrorPayload is a wrapper for an owned GraphQLError.

NextPayload

Sent after execution of an operation. For queries and mutations, this is sent to the client once. For subscriptions, this is sent for every event in the event stream.

SubscribePayload

The payload for a client’s “start” message. This triggers execution of a query, mutation, or subscription.

Enums

ClientMessage

ClientMessage defines the message types that clients can send.

Input

Possible inputs received from a client.

Output

Output provides the responses that should be sent to the client.

ServerMessage

ServerMessage defines the message types that servers can send.

Traits

Init

Init defines the requirements for types that can provide connection configurations when ConnectionInit messages are received. Implementations are provided for ConnectionConfig and closures that meet the requirements.

Schema

Schema defines the requirements for schemas that can be used for operations. Typically this is just an Arc<RootNode<...>> and you should not have to implement it yourself.
