This reverts commit 82617ac51e7825db53451818f4d1ad52b69761fd. Reason for revert: Break downstream projects Original change's description: > Rename `requested_resolution` to `scale_resolution_down_to`. > > This is a pure refactor/rename CL without any changes in behavior. > > This field is called scaleResolutionDownTo in the spec and JavaScript. > Let's make C++ match to avoid confusion. > > In order not to break downstream during the transition a variable with > the old name being a pure reference to the renamed attribute is added. > This means we have to add custom constructors, but we can change this > back to "= default" when the transition is completed, which should only > be a couple of CLs away. > > Bug: webrtc:375048799 > Change-Id: If755102ccd79d46020ce5b33acd3dfcc29799e47 > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/366560 > Reviewed-by: Ilya Nikolaevskiy <ilnik@webrtc.org> > Reviewed-by: Henrik Andreassson <henrika@webrtc.org> > Commit-Queue: Henrik Boström <hbos@webrtc.org> > Cr-Commit-Position: refs/heads/main@{#43300} Bug: webrtc:375048799 Change-Id: Ie41723a39420e12e7b5b681d3d00ccd14f66b4b1 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/366642 Reviewed-by: Harald Alvestrand <hta@webrtc.org> Commit-Queue: Florent Castelli <orphis@webrtc.org> Bot-Commit: rubber-stamper@appspot.gserviceaccount.com <rubber-stamper@appspot.gserviceaccount.com> Cr-Commit-Position: refs/heads/main@{#43301}
How to write code in the api/ directory
Mostly, just follow the regular style guide, but:
- Note that
api/code is not exempt from the “.hand.ccfiles come in pairs” rule, so if you declare something inapi/path/to/foo.h, it should be defined inapi/path/to/foo.cc. - Headers in
api/should, if possible, not#includeheaders outsideapi/. It’s not always possible to avoid this, but be aware that it adds to a small mountain of technical debt that we’re trying to shrink. .ccfiles inapi/, on the other hand, are free to#includeheaders outsideapi/.- Avoid structs in api, prefer classes.
The preferred way for api/ code to access non-api/ code is to call
it from a .cc file, so that users of our API headers won’t transitively
#include non-public headers.
For headers in api/ that need to refer to non-public types, forward
declarations are often a lesser evil than including non-public header files. The
usual rules still apply, though.
.cc files in api/ should preferably be kept reasonably small. If a
substantial implementation is needed, consider putting it with our non-public
code, and just call it from the api/ .cc file.
Avoid defining api with structs as it makes harder for the api to evolve. Your struct may gain invariant, or change how it represents data. Evolving struct from the api is particular challenging as it is designed to be used in other code bases and thus needs to be updated independetly from its usage. Class with accessors and setters makes such migration safer. See Google C++ style guide for more.
If you need to evolve existent struct in api, prefer first to convert it into a class.
