Module eth

Expand description

Interact with the eth provider module.

Structs§

AccessSettings: Settings for our ETH provider
Address: An Ethereum address, 20 bytes in length.
Block: Block representation
Bytes: Wrapper type around bytes::Bytes to support “0x” prefixed hex strings.
ErrorPayload: A JSON-RPC 2.0 error object.
EthSub: Incoming type for successful subscription updates.
EthSubError: If your subscription is closed unexpectedly, you will receive this.
FeeHistory: Response type for eth_feeHistory
Filter: Filter for logs.
Log: Ethereum Log emitted by a transaction
Provider: An EVM chain provider. Create this object to start making RPC calls. Set the chain_id to determine which chain to call: requests will fail unless the node this process is running on has access to a provider for that chain.
ProviderConfig: Provider config. Can currently be a node or a ws provider instance.
Transaction: Transaction object used in RPC
TransactionInput: Helper type that supports both data and input fields that map to transaction input data.
TransactionReceipt: Transaction receipt
TransactionRequest: Represents all transaction requests to/from RPC.

AlloyAuthorization: Basic, bearer or raw authentication in http or websocket transport.
Authorization
BlockId: A Block Identifier. https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1898.md
BlockNumberOrTag: A block Number (or tag - “latest”, “earliest”, “pending”)
EthAction: The Action and Request type that can be made to eth:distro:sys. Any process with messaging capabilities can send this action to the eth provider.
EthConfigAction: The action type used for configuring eth:distro:sys. Only processes which have the “root” crate::Capability from eth:distro:sys can successfully send this action.
EthConfigResponse: Response type from an EthConfigAction request.
EthError
EthResponse: The crate::Response body type which a process will get from requesting with an EthAction will be of this type, serialized and deserialized using serde_json::to_vec and serde_json::from_slice.
FilterBlockOption: Represents the target range of blocks for the filter
NodeOrRpcUrl
Params: Any additional parameters for a subscription.
SubscriptionKind: Subscription kind. Pulled directly from alloy (https://github.com/alloy-rs/alloy). Why? Because alloy is not yet 1.0 and the types in this interface must be stable. If alloy SubscriptionKind changes, we can implement a transition function in runtime for this type.
SubscriptionResult: Subscription result.

BlockHash: A block hash.
BlockNumber: A block number.
EthSubResult: Incoming crate::Request containing subscription updates or errors that processes will receive. Can deserialize all incoming requests from eth:distro:sys to this type.
SavedConfigs
TxHash: A transaction hash is a keccak hash of an RLP encoded signed transaction.
U8: 8-bit unsigned integer type, consisting of 1, 64-bit limbs.
U64: 64-bit unsigned integer type, consisting of 1, 64-bit limbs.
U128: 128-bit unsigned integer type, consisting of 2, 64-bit limbs.
U256: 256-bit unsigned integer type, consisting of 4, 64-bit limbs.
