Crate pallas_configs 

Strongly typed parsers for Cardano genesis files and protocol parameters.

One module per era exposes the canonical genesis shape and a from_file helper, so tools that need to reason about staking metadata, cost models, or other configuration data don’t have to hand-roll JSON shapes.

Usage

use pallas_configs::shelley;

let config = shelley::from_file(std::path::Path::new("genesis.json"))?;

if let Some(staking) = config.staking {
    if let Some(pools) = staking.pools {
        for (pool_id, pool) in pools {
            println!("pool {pool_id} has pledge {}", pool.pledge);
        }
    }
}

Overview

• byron, shelley, alonzo, conway — one module per era, each exposing a GenesisFile (or equivalent) struct and a from_file helper.
• cost_models — typed views over Plutus cost-model tables, shared across eras.

Modules

alonzo

Alonzo-era genesis parameters (cost models, prices, max collateral).

byron

Byron-era genesis configuration. Parsing of Byron configuration data

conway

Conway-era genesis parameters (governance, committees, hard-fork init).

cost_models

Built-in Plutus V1/V2/V3 cost-model snapshots.

shelley

Shelley-era genesis configuration (network start, system start, k, …).
