Implementations

impl BandwidthProofBuilder

pub fn new() -> Self

Create a new builder.

Example

use chie_shared::types::bandwidth::BandwidthProofBuilder;

let proof = BandwidthProofBuilder::new()
    .content_cid("bafybeigdyrzt5sfp7udm7hu76uh7y26nf3efuylqabf3oclgtqy55fbzdi")
    .chunk_index(0)
    .bytes_transferred(262_144)
    .provider_peer_id("12D3KooWProviderPeerID")
    .requester_peer_id("12D3KooWRequesterPeerID")
    .provider_public_key(vec![1u8; 32])
    .requester_public_key(vec![2u8; 32])
    .provider_signature(vec![3u8; 64])
    .requester_signature(vec![4u8; 64])
    .challenge_nonce(vec![5u8; 32])
    .chunk_hash(vec![6u8; 32])
    .timestamps(1000, 1100)
    .build()
    .expect("Failed to build bandwidth proof");

assert_eq!(proof.bytes_transferred, 262_144);
assert_eq!(proof.latency_ms, 100);
assert!(proof.is_valid());
assert_eq!(proof.bandwidth_bps(), 2_621_440.0);
