Expand description

A middleware allows customizing requests send and received from an ethereum node.

Writing a middleware is as simple as:

implementing the inner method to point to the next layer in the “middleware onion”, 2. implementing the MiddlewareError trait on your middleware’s error type 3. implementing any of the methods you want to override

use ethers_providers::{Middleware, MiddlewareError};
use ethers_core::types::{U64, TransactionRequest, U256, transaction::eip2718::TypedTransaction, BlockId};
use thiserror::Error;
use async_trait::async_trait;

#[derive(Debug)]
struct MyMiddleware<M>(M);

#[derive(Error, Debug)]
pub enum MyError<M: Middleware> {
    #[error("{0}")]
    MiddlewareError(M::Error),

    // Add your middleware's specific errors here
}

impl<M: Middleware> MiddlewareError for MyError<M> {
    type Inner = M::Error;

    fn from_err(src: M::Error) -> MyError<M> {
        MyError::MiddlewareError(src)
    }

    fn as_inner(&self) -> Option<&Self::Inner> {
        match self {
            MyError::MiddlewareError(e) => Some(e),
            _ => None,
        }
    }
}

#[async_trait]
impl<M> Middleware for MyMiddleware<M>
where
    M: Middleware,
{
    type Error = MyError<M>;
    type Provider = M::Provider;
    type Inner = M;

    fn inner(&self) -> &M {
        &self.0
    }

    /// Overrides the default `get_block_number` method to always return 0
    async fn get_block_number(&self) -> Result<U64, Self::Error> {
        Ok(U64::zero())
    }

    /// Overrides the default `estimate_gas` method to log that it was called,
    /// before forwarding the call to the next layer.
    async fn estimate_gas(&self, tx: &TypedTransaction, block: Option<BlockId>) -> Result<U256, Self::Error> {
        println!("Estimating gas...");
        self.inner().estimate_gas(tx, block).await.map_err(MiddlewareError::from_err)
    }
}

Required Associated Types§

source

type Error: MiddlewareError<Inner = <<Self as Middleware>::Inner as Middleware>::Error>

Error type returned by most operations

source

type Provider: JsonRpcClient

The JSON-RPC client type at the bottom of the stack

source

type Inner: Middleware<Provider = Self::Provider>

The next-lower middleware in the middleware stack

Required Methods§

source

fn inner(&self) -> &Self::Inner

Get a reference to the next-lower middleware in the middleware stack

Provided Methods§

source

fn convert_err(p: ProviderError) -> Self::Error

Convert a provider error into the associated error type by successively converting it to every intermediate middleware error

source

fn provider(&self) -> &Provider<Self::Provider>

The HTTP or Websocket provider.

source

fn default_sender(&self) -> Option<Address>

Return the default sender (if any). This will typically be the connected node’s first address, or the address of a Signer in a lower middleware stack

source

fn client_version<'life0, 'async_trait>( &'life0 self ) -> Pin<Box<dyn Future<Output = Result<String, Self::Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns the current client version using the web3_clientVersion RPC.

source

fn fill_transaction<'life0, 'life1, 'async_trait>( &'life0 self, tx: &'life1 mut TypedTransaction, block: Option<BlockId> ) -> Pin<Box<dyn Future<Output = Result<(), Self::Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Fill necessary details of a transaction for dispatch

This function is defined on providers to behave as follows:

populate the from field with the default sender
resolve any ENS names in the tx to field
Estimate gas usage
Poll and set legacy or 1559 gas prices
Set the chain_id with the provider’s, if not already set

It does NOT set the nonce by default.

Middleware are encouraged to override any values before delegating to the inner implementation AND/OR modify the values provided by the default implementation after delegating.

E.g. a middleware wanting to double gas prices should consider doing so after delegating and allowing the default implementation to poll gas.
