Struct WsClient

pub struct WsClient { /* private fields */ }

Generic asynchronous client.

Implementations

impl Client

pub fn builder() -> ClientBuilder

Create a builder for the server.

pub fn is_connected(&self) -> bool

Checks if the client is connected to the target.

pub async fn disconnect_reason(&self) -> Error

This is similar to Client::on_disconnect but it can be used to get the reason why the client was disconnected but it’s not cancel-safe.

The typical use-case is that this method will be called after Client::on_disconnect has returned in a “select loop”.

Cancel-safety

This method is cancel-safe

pub async fn on_disconnect(&self)

Completes when the client is disconnected or the client’s background task encountered an error. If the client is already disconnected, the future produced by this method will complete immediately.

Cancel safety

This method is cancel safe.

Trait Implementations

impl ClientT for Client

fn notification<'life0, 'life1, 'async_trait, Params>( &'life0 self, method: &'life1 str, params: Params, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Params: ToRpcParams + Send + 'async_trait, Client: 'async_trait,

Send a notification request

fn request<'life0, 'life1, 'async_trait, R, Params>( &'life0 self, method: &'life1 str, params: Params, ) -> Pin<Box<dyn Future<Output = Result<R, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, R: DeserializeOwned + 'async_trait, Params: ToRpcParams + Send + 'async_trait, Client: 'async_trait,

Send a method call request.

fn batch_request<'a, 'life0, 'async_trait, R>( &'life0 self, batch: BatchRequestBuilder<'a>, ) -> Pin<Box<dyn Future<Output = Result<BatchResponse<'a, R>, Error>> + Send + 'async_trait>>

where 'a: 'async_trait, 'life0: 'async_trait, R: DeserializeOwned + 'async_trait, Client: 'async_trait,

Send a batch request.

impl Debug for Client

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

Formats the value using the given formatter.

impl Drop for Client

fn drop(&mut self)

Executes the destructor for this type.

impl<Block: BlockT> HeaderProvider<Block> for WsClient

where Block::Header: DeserializeOwned,

fn get_header<'life0, 'async_trait>( &'life0 self, hash: Block::Hash, ) -> Pin<Box<dyn Future<Output = Block::Header> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Awaits for the header of the block with hash hash.

impl SubscriptionClientT for Client

fn subscribe<'a, 'life0, 'async_trait, Notif, Params>( &'life0 self, subscribe_method: &'a str, params: Params, unsubscribe_method: &'a str, ) -> Pin<Box<dyn Future<Output = Result<Subscription<Notif>, Error>> + Send + 'async_trait>>

where 'a: 'async_trait, 'life0: 'async_trait, Params: ToRpcParams + Send + 'async_trait, Notif: DeserializeOwned + 'async_trait, Client: 'async_trait,

Send a subscription request to the server.

The subscribe_method and params are used to ask for the subscription towards the server. The unsubscribe_method is used to close the subscription.

fn subscribe_to_method<'a, 'life0, 'async_trait, N>( &'life0 self, method: &'a str, ) -> Pin<Box<dyn Future<Output = Result<Subscription<N>, Error>> + Send + 'async_trait>>

where 'a: 'async_trait, 'life0: 'async_trait, N: DeserializeOwned + 'async_trait, Client: 'async_trait,

Subscribe to a specific method.
