[libcamera-devel] [PATCH v3 0/4] generate and use fixed-sized Span Control types

[Christian Rauch]

Hello,

This is version 3 of my fixed-sized Span patch set. It reverts my earlier changes to the Span constructors in order to keep compatibility with std::span. Since this prevents the default construction of fixed-sized Span, I am introducing std::optional<> to handle failure causes (when a requested ControlValue does not exist).

Best,
Christian
