types

Core types for gleeth’s JSON-RPC layer - request/response structures, Ethereum method definitions, and the unified application error type.

Types

EthMethod

</>

Supported Ethereum JSON-RPC method names.

pub type EthMethod {
  EthBlockNumber
  EthGetBalance
  EthCall
  EthGetTransactionByHash
  EthGetTransactionReceipt
  EthGetCode
  EthEstimateGas
  EthGetStorageAt
  EthGetLogs
  EthGetBlockByNumber
  EthGetBlockByHash
  EthChainId
  EthSendRawTransaction
  EthGetTransactionCount
  EthGasPrice
  EthMaxPriorityFeePerGas
  EthFeeHistory
}

Constructors

```

GleethError

</>

Unified error type for all gleeth operations. Commands return Result(Nil, GleethError), making this the single error channel across the entire application.

pub type GleethError {
  InvalidRpcUrl(String)
  InvalidAddress(String)
  InvalidHash(String)
  RpcError(String)
  NetworkError(String)
  ParseError(String)
  ConfigError(String)
  AbiErr(types.AbiError)
  WalletErr(wallet.WalletError)
  TransactionErr(transaction.TransactionError)
}

Constructors

```
InvalidRpcUrl(String)
```
The provided RPC URL is malformed or empty.
```
InvalidAddress(String)
```
The provided Ethereum address fails validation (bad length, missing 0x prefix, etc.).
```
InvalidHash(String)
```
The provided transaction or block hash fails validation.
```
RpcError(String)
```
The Ethereum node returned a JSON-RPC error response.
```
NetworkError(String)
```
A network-level failure occurred (connection refused, timeout, DNS failure).
```
ParseError(String)
```
Failed to parse a JSON-RPC response or decode a hex value.
```
ConfigError(String)
```
Invalid or missing CLI configuration (missing RPC URL, bad flags).
```
AbiErr(types.AbiError)
```
Wraps an ABI encoding/decoding error, preserving the original AbiError.
```
WalletErr(wallet.WalletError)
```
Wraps a wallet operation error, preserving the original WalletError.
```
TransactionErr(transaction.TransactionError)
```
Wraps a transaction signing/building error, preserving the original TransactionError.

JsonRpcError

</>

The error object returned inside a JSON-RPC error response.

pub type JsonRpcError {
  JsonRpcError(code: Int, message: String, data: json.Json)
}

Constructors

JsonRpcError(code: Int, message: String, data: json.Json)

JsonRpcRequest

</>

A JSON-RPC 2.0 request to be sent to an Ethereum node.

pub type JsonRpcRequest {
  JsonRpcRequest(
    jsonrpc: String,
    method: String,
    params: List(json.Json),
    id: Int,
  )
}

Constructors

JsonRpcRequest(
  jsonrpc: String,
  method: String,
  params: List(json.Json),
  id: Int,
)

JsonRpcResponse

</>

A JSON-RPC 2.0 response received from an Ethereum node.

pub type JsonRpcResponse {
  JsonRpcResponse(
    jsonrpc: String,
    id: Int,
    result: Result(json.Json, JsonRpcError),
  )
}

Constructors

JsonRpcResponse(
  jsonrpc: String,
  id: Int,
  result: Result(json.Json, JsonRpcError),
)

Values

error_to_string

</>

pub fn error_to_string(error: GleethError) -> String

Convert a GleethError to a human-readable message string.

method_to_string

</>

pub fn method_to_string(method: EthMethod) -> String

Convert an EthMethod variant to its JSON-RPC method name string.
