Struct SigningClientBuilder 

pub struct SigningClientBuilder { /* private fields */ }

Builds a SigningClient whose chain id is optional.

Omit chain_id and the client reads it from the endpoint itself on first submission, then caches it. Supply it and no lookup ever happens.

Examples

use sdk::{Client, SigningClient, crypto::Signer};

// chain id read from the endpoint
let client = SigningClient::builder(signer.clone())
    .url("http://localhost:1789")
    .build()?;

// chain id supplied — no round-trip
let client = SigningClient::builder(signer.clone())
    .url("http://localhost:1789")
    .chain_id("real-t-0001")
    .build()?;

// many signers over one connection pool, sharing its chain-id lookup
let shared = Client::new("http://localhost:1789")?;
let client = SigningClient::builder(signer).client(shared).build()?;

Implementations

impl SigningClientBuilder

pub fn url(self, url: impl Into<String>) -> SigningClientBuilder

Endpoint to trade against, replacing any endpoint already set.

pub fn client(self, client: Client) -> SigningClientBuilder

Reuses an existing Client, sharing its connection pool and its chain-id cache. Prefer this when building many signers against one endpoint — it avoids connection storms and repeated chain-id lookups.

pub fn chain_id(self, chain_id: impl Into<String>) -> SigningClientBuilder

Chain id to sign with. Omit to read it from the endpoint instead.

pub fn build(self) -> Result<SigningClient>

Errors

Fails if no endpoint was set, or if the URL set is not a valid one.
