Struct FlashbotsMiddleware

pub struct FlashbotsMiddleware<P, T> {
    provider: P,
    relay: Relay,
    simulation_relay: Option<Relay>,
    _t: PhantomData<T>,
}

Fields

provider: P

relay: Relay

simulation_relay: Option<Relay>

_t: PhantomData<T>

Implementations

impl<P, T> FlashbotsMiddleware<P, T>

where T: Transport + Clone, P: Provider<T, Ethereum> + Send + Sync + Clone + 'static,

pub fn new(relay_url: impl Into<Url>, provider: P) -> Self

Initialize a new Flashbots middleware.

The signer is used to sign requests to the relay.

pub fn new_no_signer(relay_url: impl Into<Url>, provider: P) -> Self

pub fn relay(&self) -> &Relay

Get the relay client used by the middleware.

pub fn simulation_relay(&self) -> Option<&Relay>

Get the relay client used by the middleware to simulate bundles if set.

pub fn set_simulation_relay(&mut self, relay_url: impl Into<Url>)

Set a separate relay to use for simulating bundles.

This can either be a full Flashbots relay or a node that implements the eth_callBundle remote procedure call.

pub async fn simulate_bundle( &self, bundle: &BundleRequest, ) -> Result<SimulatedBundle, FlashbotsMiddlewareError>

Simulate a bundle.

See eth_callBundle for more information.

pub async fn simulate_local_bundle( &self, bundle: &BundleRequest, ) -> Result<SimulatedBundle, FlashbotsMiddlewareError>

pub async fn send_bundle( &self, bundle: &BundleRequest, ) -> Result<(), FlashbotsMiddlewareError>

Send a bundle to the relayer.

See eth_sendBundle for more information.

Trait Implementations

impl<P: Clone, T: Clone> Clone for FlashbotsMiddleware<P, T>

fn clone(&self) -> FlashbotsMiddleware<P, T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
