[PATCH v3 1/9] qapi: replace List[str] by QAPISchemaIfCond

[PATCH v3 1/9] qapi: replace List[str] by QAPISchemaIfCond |
|
Date: |
Thu, 29 Apr 2021 17:40:24 +0400 |
From: Marc-André Lureau <marcandre.lureau@redhat.com>
Wrap the 'if' condition in a higher-level object. Not only this allows
more type safety but also further refactoring without too much churn.
The following patches will change the syntax of the schema 'if'
conditions to be predicate expressions, and will generate code for
different target languages (C, and Rust in another series).
Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com>
