Struct juniper_graphql_ws::ConnectionConfig

pub struct ConnectionConfig<CtxT> {
    pub context: CtxT,
    pub max_in_flight_operations: usize,
    pub keep_alive_interval: Duration,
}

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

Fields

context: CtxT

Custom-provided juniper::Context.

max_in_flight_operations: usize

Maximum number of in-flight operations that a connection can have.

If this number is exceeded, attempting to start more will result in an error. By default, there is no limit to in-flight operations.

keep_alive_interval: Duration

Interval at which to send keep-alives.

Specifying a Duration::ZERO will disable keep-alives.

By default, keep-alives are sent every 15 seconds.

Implementations

impl<CtxT> ConnectionConfig<CtxT>

pub fn new(context: CtxT) -> Self

Constructs the configuration required for a connection to be accepted.

pub fn with_max_in_flight_operations(self, max: usize) -> Self

Specifies the maximum number of in-flight operations that a connection can have.

If this number is exceeded, attempting to start more will result in an error. By default, there is no limit to in-flight operations.

pub fn with_keep_alive_interval(self, interval: Duration) -> Self

Specifies the interval at which to send keep-alives.

Specifying a Duration::ZERO will disable keep-alives.

By default, keep-alives are sent every 15 seconds.

Trait Implementations

impl<CtxT: Clone> Clone for ConnectionConfig<CtxT>

fn clone(&self) -> ConnectionConfig<CtxT>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<CtxT: Debug> Debug for ConnectionConfig<CtxT>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S: ScalarValue, CtxT: Unpin + Send + 'static> Init<S, CtxT> for ConnectionConfig<CtxT>

type Error = Infallible

The error that is returned on failure. The formatted error will be used as the contents of the “message” field sent back to the client.

type Future = Ready<Result<ConnectionConfig<CtxT>, <ConnectionConfig<CtxT> as Init<S, CtxT>>::Error>>

The future configuration type.

fn init(self, _params: Variables<S>) -> Self::Future

Returns a future for the configuration to use.
