Struct Client 

pub struct Client { /* private fields */ }

Client defines functions to communicate with ParallelChain RPC endpoints. Users are required to provide corresponding request specified in pchain_types in order to get a correct response.

Implementations

impl Client

pub fn new(rpc_base_url: &str) -> Self

new creates a new instance of a pchain_client given a network provider.

Arguments

• rpc_base_url - base URL of Parallelchain RPC endpoints

pub fn set_provider(&mut self, rpc_base_url: &str)

set_provider assigns new network provider for Client.

Arguments

• rpc_base_url - base URL of Parallelchain RPC endpoints

pub async fn is_provider_up(&self) -> (String, bool)

is_provider_up returns the current network provider for Client, and check if the current provider is up.

Return

Tuple of (provider url, boolean). Returns true if server is up, otherwise returns false.
