[][src]Crate ethers_providers

Clients for interacting with Ethereum nodes

This crate provides asynchronous Ethereum JSON-RPC compliant clients.

For more documentation on the available calls, refer to the Provider struct.

Examples

use ethers::providers::{Provider, Http};
use std::convert::TryFrom;

let provider = Provider::<Http>::try_from(
    "https://mainnet.infura.io/v3/c60b0bb42f8a4c6481ecd229eddaca27"
)?;

let block = provider.get_block(100u64).await?;
println!("Got block: {}", serde_json::to_string(&block)?);

let code = provider.get_code("0x89d24a6b4ccb1b6faa2625fe562bdd9a23260359", None).await?;
println!("Got code: {}", serde_json::to_string(&code)?);

Ethereum Name Service

The provider may also be used to resolve Ethereum Name Service (ENS) names to addresses (and vice versa). The default ENS address is mainnet and can be overriden by calling the ens method on the provider.

// Resolve ENS name to Address
let name = "vitalik.eth";
let address = provider.resolve_name(name).await?;

// Lookup ENS name given Address
let resolved_name = provider.lookup_address(address).await?;
assert_eq!(name, resolved_name);

Structs

Http

A low-level JSON-RPC Client over HTTP.

PendingTransaction

A pending transaction is a transaction which has been submitted but is not yet mined. await'ing on a pending transaction will resolve to a transaction receipt once the transaction has enough confirmations. The default number of confirmations is 1, but may be adjusted with the confirmations method. If the transaction does not have enough confirmations or is not mined, the future will stay in the pending state.

Provider

An abstract provider for interacting with the Ethereum JSON RPC API. Must be instantiated with a data transport which implements the JsonRpcClient trait (e.g. HTTP, Websockets etc.)

Enums

ProviderError

An error thrown when making a call to the provider

Traits

FilterStream

Trait for streaming filters.

JsonRpcClient

Trait which must be implemented by data transports to be used with the Ethereum JSON-RPC provider.

StreamExt

An extension trait for Streams that provides a variety of convenient combinator functions.
