Surfnet

pub struct Surfnet { /* private */ }

Constructores

impl Surfnet {
    pub async fn start() -> SurfnetResult<Self>;
    pub fn builder() -> SurfnetBuilder;
}

Accesores

impl Surfnet {
    pub fn rpc_url(&self) -> &str;
    pub fn ws_url(&self) -> &str;
    pub fn payer(&self) -> &Keypair;
    pub fn instance_id(&self) -> &str;
    pub fn rpc_client(&self) -> RpcClient;
    pub fn cheatcodes(&self) -> Cheatcodes<'_>;
    pub fn events(&self) -> &crossbeam_channel::Receiver<SimnetEvent>;
    pub fn send_command(&self, cmd: SimnetCommand) -> SurfnetResult<()>;
}

Ciclo de vida

impl Surfnet {
    pub fn stop(&mut self) -> SurfnetResult<()>;
}

impl Drop for Surfnet { /* calls stop() if not already stopped */ }

stop espera hasta cinco segundos para que el runtime libere sus puertos. Un fallo durante Drop es silencioso; un fallo durante un stop explícito devuelve un SurfnetError::Runtime.

SurfnetBuilder

pub struct SurfnetBuilder { /* private */ }

Cada setter devuelve Self, por lo que las llamadas pueden encadenarse. La llamada terminal es start().await.

impl SurfnetBuilder {
    pub fn offline(self, offline: bool) -> Self;
    pub fn remote_rpc_url(self, url: impl Into<String>) -> Self;
    pub fn block_production_mode(self, mode: BlockProductionMode) -> Self;
    pub fn slot_time_ms(self, ms: u64) -> Self;
    pub fn airdrop_addresses(self, addrs: Vec<Pubkey>) -> Self;
    pub fn airdrop_sol(self, lamports: u64) -> Self;
    pub fn skip_blockhash_check(self, skip: bool) -> Self;
    pub fn payer(self, payer: Keypair) -> Self;
    pub fn enable_feature(self, feature_id: Pubkey) -> Self;
    pub fn disable_feature(self, feature_id: Pubkey) -> Self;
    pub fn feature_config(self, config: SvmFeatureConfig) -> Self;
    pub async fn start(self) -> SurfnetResult<Surfnet>;
}

Cheatcodes

pub struct Cheatcodes<'a> { /* private */ }

Financiación con SOL

impl<'a> Cheatcodes<'a> {
    pub fn fund_sol(&self, address: &Pubkey, lamports: u64) -> SurfnetResult<()>;
    pub fn fund_sol_many(&self, accounts: &[(&Pubkey, u64)]) -> SurfnetResult<()>;
}

Financiación de tokens

impl<'a> Cheatcodes<'a> {
    pub fn fund_token(
        &self,

        mint: &Pubkey,
        amount: u64,
        token_program: Option<&Pubkey>,
    ) -> SurfnetResult<()>;

    pub fn fund_token_many(
        &self,
        owners: &[&Pubkey],
        mint: &Pubkey,
        amount: u64,
        token_program: Option<&Pubkey>,
    ) -> SurfnetResult<()>;

    pub fn set_token_balance(
        &self,
        owner: &Pubkey,
        mint: &Pubkey,
        amount: u64,
        token_program: Option<&Pubkey>,
    ) -> SurfnetResult<()>;

    pub fn get_ata(
        &self,
        owner: &Pubkey,
        mint: &Pubkey,
        token_program: Option<&Pubkey>,
    ) -> Pubkey;
}

Mutación de cuenta

impl<'a> Cheatcodes<'a> {
    pub fn set_account(
        &self,
        address: &Pubkey,
        lamports: u64,
        data: &[u8],
        owner: &Pubkey,
    ) -> SurfnetResult<()>;

    pub fn execute<B: CheatcodeBuilder>(&self, builder: B) -> SurfnetResult<()>;
}

Viaje en el Tiempo

impl<'a> Cheatcodes<'a> {
    pub fn time_travel_to_slot(&self, slot: u64) -> SurfnetResult<EpochInfo>;
    pub fn time_travel_to_epoch(&self, epoch: u64) -> SurfnetResult<EpochInfo>;
    pub fn time_travel_to_timestamp(&self, timestamp_ms: u64) -> SurfnetResult<EpochInfo>;
}

Despliegue de Programas

impl<'a> Cheatcodes<'a> {
    pub fn deploy_program(&self, program_name: &str) -> SurfnetResult<Pubkey>;
    pub fn deploy(&self, builder: DeployProgram) -> SurfnetResult<Pubkey>;
}

Trait CheatcodeBuilder

pub trait CheatcodeBuilder {
    const METHOD: &'static str;
    fn build(self) -> serde_json::Value;
}

Implementa esto para cheatcodes JSON-RPC personalizados que aún no están envueltos por un constructor tipado.

Constructores

Todos los constructores se encuentran en surfpool_sdk::cheatcodes::builders.

impl SetAccount {
    pub fn new(address: Pubkey) -> Self;
    pub fn lamports(self, lamports: u64) -> Self;
    pub fn data(self, data: Vec<u8>) -> Self;
    pub fn owner(self, owner: Pubkey) -> Self;
    pub fn rent_epoch(self, epoch: u64) -> Self;
    pub fn executable(self, executable: bool) -> Self;
}

pub struct SetTokenAccount { /* private */ }

impl SetTokenAccount {
    pub fn new(owner: Pubkey, mint: Pubkey) -> Self;
    pub fn amount(self, amount: u64) -> Self;
    pub fn delegate(self, delegate: Pubkey) -> Self;
    pub fn clear_delegate(self) -> Self;
    pub fn state(self, state: impl Into<String>) -> Self;

    pub fn close_authority(self, authority: Pubkey) -> Self;
    pub fn clear_close_authority(self) -> Self;
    pub fn token_program(self, program: Pubkey) -> Self;
}

ResetAccount

pub struct ResetAccount { /* private */ }

impl ResetAccount {
    pub fn new(address: Pubkey) -> Self;
    pub fn include_owned_accounts(self, include: bool) -> Self;
}

StreamAccount

pub struct StreamAccount { /* private */ }

impl StreamAccount {
    pub fn new(address: Pubkey) -> Self;
    pub fn include_owned_accounts(self, include: bool) -> Self;
}

DeployProgram

pub struct DeployProgram { /* private */ }

impl DeployProgram {
    pub fn new(program_id: Pubkey) -> Self;
    pub fn from_keypair_path(path: impl AsRef<Path>) -> SurfnetResult<Self>;
    pub fn so_path(self, path: impl Into<PathBuf>) -> Self;
    pub fn so_bytes(self, bytes: Vec<u8>) -> Self;
    pub fn idl_path(self, path: impl Into<PathBuf>) -> Self;
}

SurfnetError

#[derive(Debug)]
pub enum SurfnetError {
    PortAllocation(String),
    Startup(String),
    Runtime(String),
    Cheatcode(String),
    Aborted(String),
}

Variante	Causa
`PortAllocation`	No se pudo vincular a un puerto libre para RPC o WebSocket.
`Startup`	El tiempo de ejecución no pudo inicializarse.
`Runtime`	El hilo de ejecución entró en pánico o finalizó inesperadamente.
`Cheatcode`	Una llamada JSON-RPC de cheatcode devolvió un error.
`Aborted`	El tiempo de ejecución fue detenido o cancelado durante el inicio.

El crate implementa std::error::Error y Display en SurfnetError, por lo que funciona con ? y anyhow de forma nativa.
