Struct RpcClient 

pub struct RpcClient { /* private fields */ }

A concrete wrapper around an RpcClientT which provides some higher level helper methods and is cheaply cloneable.

Implementations

impl RpcClient

pub async fn from_url<U: AsRef<str>>(url: U) -> Result<Self, Error>

Available on crate feature jsonrpsee only.

Create a default RPC client pointed at some URL, currently based on jsonrpsee.

Errors if an insecure URL is provided. In this case, use RpcClient::from_insecure_url instead.

pub async fn from_insecure_url<U: AsRef<str>>(url: U) -> Result<Self, Error>

Available on crate feature jsonrpsee only.

Create a default RPC client pointed at some URL, currently based on jsonrpsee.

Allows insecure URLs without SSL encryption, e.g. (http:// and ws:// URLs).

pub fn new<R: RpcClientT>(client: R) -> Self

Create a new RpcClient from an arbitrary RpcClientT implementation.

pub async fn request<Res: DeserializeOwned>( &self, method: &str, params: RpcParams, ) -> Result<Res, Error>

Make an RPC request, given a method name and some parameters.

See RpcParams and the rpc_params! macro for an example of how to construct the parameters.

pub async fn subscribe<Res: DeserializeOwned>( &self, sub: &str, params: RpcParams, unsub: &str, ) -> Result<RpcSubscription<Res>, Error>

Subscribe to an RPC endpoint, providing the parameters and the method to call to unsubscribe from it again.

See RpcParams and the rpc_params! macro for an example of how to construct the parameters.
