Cela signifie que **FastAPI** a été spécifiquement testé avec les éditeurs utilisés par 80% des développeurs Python. Et comme la plupart des autres éditeurs ont tendance à fonctionner de façon similaire, tous ses avantages devraient fonctionner pour pratiquement tous les éditeurs.

    val relay = edit(file, pipe.source, metadata, 5)
    val future1 = executor.submit(sourceReader(relay.newSource()))
    val future2 = executor.submit(sourceReader(relay.newSource()))
