Pallas Primitives

Era-aware Cardano ledger types with their CBOR codecs. This is the data layer that the rest of the Pallas ledger crates sit on: pallas-traverse gives you a multi-era read API over these types, pallas-validate applies ledger rules to them, and pallas-txbuilder builds new ones.

If you need raw, era-specific access to a Tx, Block, or PlutusData, you want this crate. If you'd rather work over many eras through one interface, reach for pallas-traverse.

Usage

use pallas_codec::minicbor;
use pallas_primitives::conway;

let tx: conway::Tx = minicbor::decode(&cbor_bytes)?;

for input in tx.transaction_body.inputs.iter() {
    println!("{:?}#{}", input.transaction_id, input.index);
}

Overview

• byron, alonzo, babbage, conway — one module per era, each exposing the era's Block, Tx, TransactionInput, TransactionOutput, Value, Certificate, Metadata, witness sets, and so on.
• plutus_data — re-exported PlutusData, BigInt, and helpers shared across eras.
• framework — common type aliases and codec primitives (AddrKeyhash, Coin, PolicyId, RationalNumber, StakeCredential, TransactionInput, ExUnits, PlutusScript<V>, …).
• Re-exports from pallas-codec (Bytes, KeepRaw, KeyValuePairs, NonEmptySet, Set, Nullable, …) and pallas-crypto (Hash).
