pallas-hardano

Pallas Hardano

Interoperability with implementation-specific artifacts of the Haskell Cardano node. Today the main job is reading the node's immutable on-disk chunks (the immutable/ directory of a synced node), so a Rust process can iterate the chain without re-syncing.

Usage

use std::path::Path;
use pallas_hardano::storage::immutable;

for block in immutable::read_blocks(Path::new("/var/cardano/data/immutable"))? {
    let bytes = block?;
    // hand `bytes` to pallas-traverse / pallas-primitives for typed access
}

Overview

• storage::immutable — readers over the node's chunk / primary / secondary index files. Top-level entry points: read_blocks, read_blocks_from_point, get_tip.
• display — pretty-printing helpers for the structures above.
