How was this library created?

• used didc to generate the rust bindings from the evm rpc canister did file
• added call_with_payment128 to functions that expect cycles
• derive Debug and Clone trait for types for convenience

How to use this library?

• make sure you deploy the evm rpc canister to its mainnet id locally (7hfb6-caaaa-aaaar-qadga-cai)

  "evm_rpc": {
    "type": "custom",
    "candid": "https://github.com/internet-computer-protocol/evm-rpc-canister/releases/latest/download/evm_rpc.did",
    "wasm": "https://github.com/internet-computer-protocol/evm-rpc-canister/releases/latest/download/evm_rpc.wasm.gz",
    "remote": {
      "id": {
        "ic": "7hfb6-caaaa-aaaar-qadga-cai"
      }
    },
    "specified_id": "7hfb6-caaaa-aaaar-qadga-cai",
    "init_arg": "(record { nodesInSubnet = 28 })"
  }
  

• if you deploy your own evm rpc canister, you can use the EvmRpcCanister struct to initiate the canister with your own canister id

  pub const CANISTER_ID: Principal =
    Principal::from_slice(b"\x00\x00\x00\x00\x02\x30\x00\xCC\x01\x01"); // 7hfb6-caaaa-aaaar-qadga-cai
  pub const EVM_RPC: EvmRpcCanister = EvmRpcCanister(CANISTER_ID);
  

• import the libary in your rust project

  [dependencies]
  evm_rpc_canister_types = 0.1
  

• import the crate where needed, e.g.

  use evm_rpc_canister_types::{
    BlockTag, GetBlockByNumberResult, GetLogsArgs, GetLogsResult, HttpOutcallError,
    MultiGetBlockByNumberResult, MultiGetLogsResult, RejectionCode, RpcError, EVM_RPC,
  };
  

• the EVM_RPC struct exposes the EVM RPC canisters interface and is used to make inter canister calls to it

  let (result,) = EVM_RPC
    .eth_get_block_by_number(rpc_providers, None, block_tag, cycles)
    .await
    .expect("Call failed");
