Struct Chain 

pub struct Chain { /* private fields */ }

Chain the exchange is operating on.

Implementations

impl Chain

pub fn mainnet() -> Self

pub fn testnet() -> Self

pub fn custom( chain_id: u64, collateral_token: Address, deployed_at_block: u64, exchange: Address, perpetuals: Vec<PerpetualId>, ) -> Self

Chain the exchange is operating on, with the perpetual contracts to track.

An empty perpetuals list means every perpetual listed on the exchange, discovered on-chain - see Chain::perpetuals.

pub fn chain_id(&self) -> u64

pub fn collateral_token(&self) -> Address

pub fn deployed_at_block(&self) -> u64

pub fn exchange(&self) -> Address

pub fn perpetuals(&self) -> &[PerpetualId]

Perpetual contracts to track, empty (the default) meaning every perpetual listed on the exchange.

The exchange reports the set of listed contracts on-chain, so the SDK does not need to be told: an empty list makes state::SnapshotBuilder discover them at snapshot time. Configure it explicitly only to deliberately track a subset.

pub fn with_perpetuals(self, perpetuals: Vec<PerpetualId>) -> Self

Same chain, tracking only the given subset of perpetual contracts.

pub fn excluded_perpetuals(&self) -> &[PerpetualId]

Perpetual contracts to leave out of on-chain discovery.

Applies to discovery only: an explicitly configured Chain::perpetuals list is taken as given, exclusions and all, since naming a contract is a clearer statement of intent than the default set it would otherwise be filtered out of.

pub fn with_excluded_perpetuals(self, perpetuals: Vec<PerpetualId>) -> Self

Same chain, skipping the given perpetual contracts when discovering the set to track - see Chain::excluded_perpetuals.

Replaces the chain’s default exclusions rather than adding to them, so passing an empty list discovers everything the exchange lists.

Trait Implementations

impl Clone for Chain

fn clone(&self) -> Chain

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Chain

fn fmt(&self, f: &mut Formatter<'_>) -> Result
