surfpool_sdk

Struct Surfnet 

Source 
pub struct Surfnet { /* private fields */ }
Expand description

A running Surfpool instance with RPC/WS endpoints on dynamic ports.

Provides:

  • Pre-funded payer keypair
  • RpcClient connected to the local instance
  • Cheatcodes for direct state manipulation (fund accounts, set token balances, etc.)

The instance is shut down when dropped.

Implementations§

Source§

impl Surfnet

Source

pub async fn start() -> SurfnetResult<Self>

Start a surfnet with default settings (offline, transaction-mode blocks, 10 SOL payer).

Source

pub fn builder() -> SurfnetBuilder

Create a builder for custom configuration.

Source

pub fn rpc_url(&self) -> &str

The HTTP RPC URL (e.g. http://127.0.0.1:12345).

Source

pub fn ws_url(&self) -> &str

The WebSocket URL (e.g. ws://127.0.0.1:12346).

Source

pub fn rpc_client(&self) -> RpcClient

Create a new RpcClient connected to this surfnet.

Source

pub fn payer(&self) -> &Keypair

The pre-funded payer keypair.

Source

pub fn cheatcodes(&self) -> Cheatcodes<'_>

Access cheatcode helpers for direct state manipulation.

Source

pub fn events(&self) -> &Receiver<SimnetEvent>

Get a reference to the simnet events receiver for observing runtime events.

Source

pub fn send_command(&self, command: SimnetCommand) -> SurfnetResult<()>

Send a command to the simnet runtime.

Source

pub fn instance_id(&self) -> &str

The unique instance ID for this surfnet.

Source

pub fn stop(&mut self) -> SurfnetResult<()>

Gracefully shut down the surfnet, closing the HTTP + WebSocket RPC servers and freeing their ports.

Blocks until both RPC servers acknowledge shutdown or the timeout elapses. Returns an error if shutdown is not confirmed within the timeout (the port may still be bound) — callers that need a guaranteed-free port should treat this as fatal. On success, the instance is marked stopped and subsequent calls are a no-op.

Note: this drains the simnet events channel while waiting. Don’t call events() / drain_events() concurrently from another thread or shutdown acknowledgements may be lost, causing this call to time out.
