PirClient

pir_client

Struct PirClient 

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

PIR client that connects to a pir-server instance over HTTP.

Downloads Tier 0 data and YPIR parameters during connect(), then performs private queries via fetch_proof().

Implementations§

Source§

impl PirClient

Source

pub async fn with_transport( server_url: &str, transport: Arc<dyn Transport>, ) -> Result<Self>

Connect using a caller-provided HTTP transport.

Source

pub async fn fetch_proof(&self, nullifier: Fp) -> Result<ImtProofData>

Perform private Merkle path retrieval for a nullifier.

Returns circuit-ready ImtProofData with a 29-element path (25 PIR siblings + 4 empty-hash padding).

Source

pub async fn fetch_proof_with_timing( &self, nullifier: Fp, ) -> Result<(ImtProofData, NoteTiming)>

Like fetch_proof but also returns the full client+server timing breakdown for load-testing / observability.

Source

pub async fn fetch_proofs(&self, nullifiers: &[Fp]) -> Result<Vec<ImtProofData>>

Perform private Merkle path retrieval for multiple nullifiers in parallel.

All queries run concurrently via try_join_all, sharing the same PirClient (and thus the same HTTP client and Tier 0 data).
