Struct QuoteGenerator 

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

Quote generator for creating payment quotes.

Uses the node’s signing capabilities to sign quotes, which clients use to pay for storage on the Arbitrum network.

Implementations§

Source§

impl QuoteGenerator

Source

pub fn new( rewards_address: RewardsAddress, metrics_tracker: QuotingMetricsTracker, ) -> Self

Create a new quote generator without signing capability.

Call set_signer to enable quote signing.

§Arguments
  • rewards_address - The EVM address for receiving payments
  • metrics_tracker - Tracker for quoting metrics
Source

pub fn set_signer<F>(&mut self, pub_key: Vec<u8>, sign_fn: F)
where F: Fn(&[u8]) -> Vec<u8> + Send + Sync + 'static,

Set the signing function for quote generation.

§Arguments
  • pub_key - The node’s public key bytes
  • sign_fn - Function that signs bytes and returns signature
Source

pub fn can_sign(&self) -> bool

Check if the generator has signing capability.

Source

pub fn create_quote( &self, content: XorName, data_size: usize, data_type: u32, ) -> Result<PaymentQuote>

Generate a payment quote for storing data.

§Arguments
  • content - The XorName of the content to store
  • data_size - Size of the data in bytes
  • data_type - Type index of the data (0 for chunks)
§Returns

A signed PaymentQuote that the client can use to pay on-chain.

§Errors

Returns an error if signing is not configured.

Source

pub fn rewards_address(&self) -> &RewardsAddress

Get the rewards address.

Source

pub fn current_metrics(&self) -> QuotingMetrics

Get current quoting metrics.

Source

pub fn record_payment(&self)

Record a payment received (delegates to metrics tracker).

Source

pub fn record_store(&self, data_type: u32)

Record data stored (delegates to metrics tracker).
