Struct juniper_graphql_ws::Connection [−][src]
Implements the graphql-ws protocol. This is a sink for TryInto<ClientMessage> and a stream of
ServerMessage.
Implementations
impl<S, I> Connection<S, I> where
S: Schema,
I: Init<S::ScalarValue, S::Context>, [src]
S: Schema,
I: Init<S::ScalarValue, S::Context>,
pub fn new(schema: S, init: I) -> Self[src]
Creates a new connection, which is a sink for TryInto<ClientMessage> and a stream of ServerMessage.
The schema argument should typically be an Arc<RootNode<...>>.
The init argument is used to provide the context and additional configuration for
connections. This can be a ConnectionConfig if the context and configuration are already
known, or it can be a closure that gets executed asynchronously when the client sends the
ConnectionInit message. Using a closure allows you to perform authentication based on the
parameters provided by the client.
