Struct DevnetUsdcSettler 

pub struct DevnetUsdcSettler { /* private fields */ }

A devnet settler: the EscrowBondEngine state machine plus a real SPL-USDC transfer on slash. See the crate docs for the devnet-only caveat.

Implementations

impl DevnetUsdcSettler

pub fn new( rpc_url: impl Into<String>, agent: Arc<Keypair>, usdc_mint: Pubkey, beneficiary_token_account: Pubkey, config: BondConfig, ) -> Self

Construct against an explicit RPC endpoint and bond configuration.

pub fn devnet( agent: Arc<Keypair>, usdc_mint: Pubkey, beneficiary_token_account: Pubkey, ) -> Self

Convenience: the public devnet RPC with the default BondConfig.

pub fn agent_usdc_account(&self) -> Pubkey

The agent’s USDC associated-token account (the bond’s funding source).

pub fn quote_fee(&self, conviction: Conviction) -> Usdc

The inference fee for a given conviction (delegates to the inner engine).

pub fn ledger(&self) -> BondLedger

Snapshot of the honored/slashed ledger.

pub fn open_bonds(&self) -> usize

Number of bonds currently escrowed (awaiting settlement).

pub fn last_signature(&self) -> Option<Signature>

The signature of the most recent on-chain slash transfer, if any.

pub async fn settle_onchain( &self, bond: &Bond, fill: &Fill, ) -> Result<(BondOutcome, Option<Signature>)>

Like BondEngine::settle but also returns the on-chain transfer signature when the bond was slashed (None when honored).

Trait Implementations

impl BondEngine for DevnetUsdcSettler

fn settle<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, bond: &'life1 Bond, fill: &'life2 Fill, ) -> Pin<Box<dyn Future<Output = Result<BondOutcome>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Settles the bond and, on slash, performs the devnet USDC transfer. Use DevnetUsdcSettler::settle_onchain if you need the transfer signature.

fn escrow<'life0, 'life1, 'async_trait>( &'life0 self, solution: &'life1 Solution, ) -> Pin<Box<dyn Future<Output = Result<Bond>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Size and escrow a bond for a solution (conviction-weighted).
