Struct RpcClient
pub struct RpcClient { /* private fields */ }
Expand description
A concrete wrapper around an [RpcClientT
] which provides some higher level helper methods,
is cheaply cloneable, and can be handed to things like [crate::client::OnlineClient
] to
instantiate it.
Implementations§
§impl RpcClient
impl RpcClient
pub async fn from_url<U>(url: U) -> Result<RpcClient, Error>
pub async fn from_url<U>(url: U) -> Result<RpcClient, Error>
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>(url: U) -> Result<RpcClient, Error>
pub async fn from_insecure_url<U>(url: U) -> Result<RpcClient, Error>
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>(client: R) -> RpcClientwhere
R: RpcClientT,
pub fn new<R>(client: R) -> RpcClientwhere
R: RpcClientT,
Create a new RpcClient
from an arbitrary [RpcClientT
] implementation.
pub async fn request<Res>(
&self,
method: &str,
params: RpcParams,
) -> Result<Res, Error>where
Res: DeserializeOwned,
pub async fn request<Res>(
&self,
method: &str,
params: RpcParams,
) -> Result<Res, Error>where
Res: DeserializeOwned,
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>(
&self,
sub: &str,
params: RpcParams,
unsub: &str,
) -> Result<RpcSubscription<Res>, Error>where
Res: DeserializeOwned,
pub async fn subscribe<Res>(
&self,
sub: &str,
params: RpcParams,
unsub: &str,
) -> Result<RpcSubscription<Res>, Error>where
Res: DeserializeOwned,
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.
