[PATCH 13/18] qapi/crypto: Rename QCryptoIVGenAlgorithm to *Algo, and drop prefix |
|
Date: |
Tue, 30 Jul 2024 10:10:27 +0200 |
QAPI's 'prefix' feature can make the connection between enumeration
type and its constants less than obvious. It's best used with
restraint.
QCryptoIVGenAlgorithm has a 'prefix' that overrides the generated
enumeration constants' prefix to QCRYPTO_IVGEN_ALG.
We could simply drop 'prefix', but then the prefix becomes
QCRYPTO_IV_GEN_ALGORITHM, which is rather long.
We could additionally rename the type to QCryptoIVGenAlg, but I think
the abbreviation "alg" is less than clear.
Rename the type to QCryptoIVGenAlgo instead. The prefix becomes
QCRYPTO_IV_GEN_ALGO.
