Implementations§

Source§

impl ProviderBuilder

Source

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

Creates a new builder instance

Source

pub fn timeout(self, timeout: Duration) -> Self

The timeout is applied from when the request starts connecting until the response body has finished.

Default is no timeout.

Source

pub fn chain(self, chain: NamedChain) -> Self

Sets the chain of the node the provider will connect to

Source

pub fn max_retry(self, max_retry: u32) -> Self

Source

pub fn maybe_max_retry(self, max_retry: Option<u32>) -> Self

How often to retry a failed request. If None, defaults to the already-set value.

Source

pub fn maybe_initial_backoff(self, initial_backoff: Option<u64>) -> Self

The starting backoff delay to use after the first failed request. If None, defaults to the already-set value.

Source

pub fn initial_backoff(self, initial_backoff: u64) -> Self

The starting backoff delay to use after the first failed request

This is only recommend for local dev nodes

Source

pub fn jwt(self, jwt: impl Into<String>) -> Self
