Said type has a little more functionality than we need, to sketch out how we'd want to develop it moving forward if we find that it's useful elsewhere. Closes #1344. Define a type for a synchronous (blocking) view of a circuit state. 2024-03-26T16:55:03Z Nick Mathewson nickm@torproject.org 2024-03-20T14:48:01Z urn:sha1:d8a1c0af0e656643f7066ef0c8079c50aa982ad3 We'll use this as an argument for the callback that checks stream requests to make sure they're permitted. proto: Make StreamMap keep a count of open streams. 2024-03-26T16:54:31Z Nick Mathewson nickm@torproject.org 2024-03-20T14:37:03Z urn:sha1:209d60af2757ba942835a5b34ecd840da2583ecd proto: Prevent general state-transitions on StreamEnt 2024-03-26T16:54:30Z Nick Mathewson nickm@torproject.org 2024-03-20T14:28:41Z urn:sha1:62d749c1eb7730eeb025885c7d7f86a0ac8c333a We want to keep an accurate count of the number of open streams, so we have to stop exposing `&mut StreamEnt` outside of the streammap module. proto: Refactor circuit::streammap::StreamEnt 2024-03-26T16:54:06Z Nick Mathewson nickm@torproject.org 2024-03-20T14:16:02Z urn:sha1:3ccc523b89d5ed37e76d8c2be43872d9127b8596 This is the first part of a refactoring that will let us keep code from the outside of `streammap` from changing a stream from one state to another. And we need to do _that_ so that StreamMap can count how many open streams it has.
