Struct NetworkInstant 

pub struct NetworkInstant(pub HashMap<Network, NetworkTime>);

A snapshot of network states across multiple chains / data sources.

Internally a HashMap<Network, NetworkTime>, where:

• NetworkTime stores the actual point-in-time (block height or unix timestamp) together with the provider needed to query it.

use eth_prices::network::NetworkInstant;

let networks = NetworkInstant::default()
    .with_evm_provider_latest(eth_provider).await?
    .with_evm_provider_latest(sep_provider).await?
    .with_now();

Note that the above example makes a eth_chainId and eth_blockNumber query per provider supplied.

Quoting at a given network time

Start with Default::default() and chain builder methods. Each builder consumes and returns self, enabling a fluent style:

use eth_prices::network::NetworkInstant;

let networks = NetworkInstant::default()
    .with_evm_block(1.into(), 123_456_789, eth_provider)
    .with_evm_block(11155111.into(), 123_456_789, sep_provider)
    .with_fiat_timestamp(time);

For single-network convenience, start with NetworkTime::instant() instead.

Implementations

impl NetworkInstant

pub fn get(&self, network_id: &Network) -> Option<&NetworkTime>

Look up the NetworkTime for a given network.

pub fn get_evm_block( &self, network_id: Network, ) -> Option<(&NetworkId, &BlockNumber, &RpcProvider)>

Convenience accessor: extract the EVM fields for a specific chain.

Returns (chain_id, block_number, provider) if the network exists and is an EVM variant.

pub fn get_fiat_timestamp(&self) -> Option<&u64>

Convenience accessor: extract the fiat timestamp (network id 0).

pub fn with_fiat_timestamp(self, timestamp: u64) -> Self

Set a fiat timestamp at network id 0.

Used by ecb quoters to pick a date.

pub fn with_now(self) -> Result<Self, EthPricesError>

Set a fiat timestamp to the current time.

pub fn with_evm_block( self, network_id: NetworkId, block_number: BlockNumber, provider: RpcProvider, ) -> Self

Set an EVM network to a specific block number.

Use this when you already know the block height (e.g. from a historical query or configuration).

pub async fn with_evm_latest( self, network_id: NetworkId, provider: RpcProvider, ) -> Result<Self, EthPricesError>

Set an EVM network to the latest block, fetched from the RPC.

This is an async builder — it must be .awaited before further chaining:

let networks = NetworkInstant::default()
    .with_evm_latest(1, eth_provider).await?
    .with_evm_latest(42161, arb_provider).await?;

pub async fn with_evm_provider( self, provider: RpcProvider, ) -> Result<Self, EthPricesError>
