Client

type Client​

Client provides an interface for interacting with the blockchain. It is the main struct of the gnoclient package, exposing all APIs used to communicate with a Gno.land chain.

type Client struct {
    Signer    Signer           // Signer for transaction authentication
    RPCClient rpcclient.Client // RPC client for blockchain communication
}

func (*Client) AddPackage​

func (c *Client) AddPackage(cfg BaseTxCfg, msgs ...MsgAddPackage) (*ctypes.ResultBroadcastTxCommit, error)

AddPackage executes one or more AddPackage calls on the blockchain.

func (*Client) Call​

func (c *Client) Call(cfg BaseTxCfg, msgs ...MsgCall) (*ctypes.ResultBroadcastTxCommit, error)

Call executes a one or more MsgCall calls on the blockchain.

func (*Client) Send​

func (c *Client) Send(cfg BaseTxCfg, msgs ...MsgSend) (*ctypes.ResultBroadcastTxCommit, error)

Send executes one or more MsgSend calls on the blockchain.

func (*Client) Run​

func (c *Client) Run(cfg BaseTxCfg, msgs ...MsgRun) (*ctypes.ResultBroadcastTxCommit, error)

Run executes a one or more MsgRun calls on the blockchain.

func (*Client) QEval​

func (c *Client) QEval(pkgPath string, expression string) (string, *ctypes.ResultABCIQuery, error)

QEval evaluates the given expression with the realm code at pkgPath. The pkgPath should include the prefix like gno.land/. The expression is usually a function call like Render("").

func (*Client) Query​

func (c *Client) Query(cfg QueryCfg) (*ctypes.ResultABCIQuery, error)

Query performs a generic query on the blockchain.

func (*Client) QueryAccount​

func (c *Client) QueryAccount(addr crypto.Address) (*std.BaseAccount, *ctypes.ResultABCIQuery, error)

QueryAccount retrieves account information for a given address.

func (*Client) QueryAppVersion​

func (c *Client) QueryAppVersion() (string, *ctypes.ResultABCIQuery, error)

QueryAppVersion retrieves information about the Gno.land app version.

func (*Client) Render​

func (c *Client) Render(pkgPath string, args string) (string, *ctypes.ResultABCIQuery, error)

Render calls the Render function for pkgPath with optional args. The pkgPath should include the prefix like gno.land/. This is similar to using a browser URL <testnet>/<pkgPath>:<args> where <pkgPath> doesn't have the prefix like gno.land/.

type BaseTxCfg​

BaseTxCfg defines the base transaction configuration, shared by all message types.

type BaseTxCfg struct {
    GasFee         string // Gas fee
    GasWanted      int64  // Gas wanted
    AccountNumber  uint64 // Account number
    SequenceNumber uint64 // Sequence number
    Memo           string // Memo
}

type MsgAddPackage​

MsgAddPackage - syntax sugar for vm.MsgAddPackage.

type MsgAddPackage struct {
    Package *std.MemPackage // Package to add
    Deposit string          // Coin deposit
}

type MsgCall​

MsgCall - syntax sugar for vm.MsgCall.

type MsgCall struct {
    PkgPath  string   // Package path
    FuncName string   // Function name
    Args     []string // Function arguments
    Send     string   // Send amount
}

type MsgRun​

MsgRun - syntax sugar for vm.MsgRun.

type MsgRun struct {
    Package *std.MemPackage // Package to run
    Send    string          // Send amount
}

type MsgSend​

MsgSend - syntax sugar for bank.MsgSend.

type MsgSend struct {
    ToAddress crypto.Address // Send to address
    Send      string         // Send amount
}

type QueryCfg​

QueryCfg contains configuration options for performing ABCI queries.

type QueryCfg struct {
    Path                       string // Query path
    Data                       []byte // Query data
    rpcclient.ABCIQueryOptions        // ABCI query options
}
