Ordering follows the ledger's Ord (Credential kr), which is derived on ScriptHashObj | KeyHashObj (libs/cardano-ledger-core/.../Credential.hs:98-101), so script credentials sort before key credentials.

Ordering follows the ledger's Ord (Credential kr), which is derived on ScriptHashObj | KeyHashObj (libs/cardano-ledger-core/.../Credential.hs:98-101), so script credentials sort before key credentials.

That is the opposite of the Plutus constructor tags (PubKeyCredential is 0, ScriptCredential is 1), and it is deliberate: V3 delivers txInfoWdrl keyed by the ledger's Credential, converted only after Map.toList has fixed the order (Conway/TxInfo.hs:697-699, :549-551). Ordering by the Plutus tags instead made withdrawals.get return None for a key that is present.

Note this does NOT apply to StakingCredential, which V1/V2 deliver in Plutus order. See the Ord[StakingCredential] instance below.

Extensions

extension (self: Credential)
inline def pubKeyHashOrFail(inline message: String): PubKeyHash

The key hash of a PubKeyCredential, or fails with message for a script credential.

The key hash of a PubKeyCredential, or fails with message for a script credential.

A direct match with no intermediate Option, unlike pubKeyOption.getOrFail(message).

Attributes

Example 
 Credential.PubKeyCredential(pkh).pubKeyHashOrFail("expected a key") === pkh
 Credential.ScriptCredential(hash).pubKeyHashOrFail("expected a key") // fails
inline def scriptHashOrFail(inline message: String): ValidatorHash

The script hash of a ScriptCredential, or fails with message for a key credential.

The script hash of a ScriptCredential, or fails with message for a key credential.

A direct match with no intermediate Option, unlike scriptOption.getOrFail(message), which allocates one that nothing folds away.

Attributes

Example 
 Credential.ScriptCredential(hash).scriptHashOrFail("expected a script") === hash
 Credential.PubKeyCredential(pkh).scriptHashOrFail("expected a script") // fails
