Paul van Tilburg	4920ab4abd	Drop Weerplaza precipitation maps (closes: #8 )	2022-02-17 21:47:01 +01:00
Paul van Tilburg	f67f3dfe82	Only update the cache if retrieval yielded maps * Add `is__stale` methods to the `MapRefresh` trait Only update the maps of a type if `retrieve_image` yielded something or if the maps are stale * Also only then bump the timestamp for the map type This means if there is nothing in the cache, it will retry each refresh to get something because the timestamp is not bumped until there is something. Once there are maps, it will only update it and bump the timestamp if there is an image, that or, it has become stale and it can be set to `None` and we end up in the initial state.	2022-02-17 21:38:41 +01:00
Paul van Tilburg	8d2717b392	Provide not the first map but an instant-relative map This calculates which offset to use in the maps series with respect to the instant of caching. It assumes the first map is current for the instant it was retrieved. * Rename `_first` to `_at` methods * For convenience, change the types of `_MAP_COUNT` to `u32` Introduce `_MAP_INTERVAL` constants to indicate the number of seconds each map in the series applies to Return `None` if the provided instant is too far in the future	2022-02-17 21:38:16 +01:00
Paul van Tilburg	88b24a83ff	Move blocking image load to separate task	2022-02-16 22:02:32 +01:00
Paul van Tilburg	9531114eec	Add methods to get the first map of each type Also introduce constants for the number of maps included in a single `DynamicImage`.	2022-02-15 17:04:04 +01:00
Paul van Tilburg	b2f63db6b4	Mention open issues in documentation; tweak docs	2022-02-15 14:15:21 +01:00
Paul van Tilburg	c231447ce9	Be pedantic with constant number notation 😉	2022-02-13 21:31:12 +01:00
Paul van Tilburg	859288a329	Increase the refresh intervals; improve documentation	2022-02-13 21:24:26 +01:00
Paul van Tilburg	309c79d83c	Disable retrieving precipitation maps for now (see #8 )	2022-02-13 21:23:48 +01:00
Paul van Tilburg	576bcc6640	Fix UV index maps base URL The typo was introduced in commit `d432bb4`.	2022-02-13 16:55:21 +01:00
Paul van Tilburg	f6b26c9659	Fix expect message	2022-02-13 16:55:03 +01:00
Paul van Tilburg	d432bb4cd6	Use URL objects instead of formatted strings Use `request::Url` for this, so we don't have to depend on the `url` crate ourselves. Also, make the URL constants more uniform.	2022-02-13 13:10:12 +01:00
Paul van Tilburg	cbd686bd60	Small documentation improvements	2022-02-13 11:22:22 +01:00
Paul van Tilburg	cf77dbb5e7	Refactor maps cache to hold lock as short as possible This makes the response time way more snappy when the maps thread is updating its cache. * Move the `MapsHandle` type to the `maps` module * SWitch to using the standard library mutex * Split refresh methods into retrieval methods that don't need the lock and check timestamp & update methods that only need it shortly * Introduce the `MapsRefresh` trait and implement it for `MapsHandle` * Reorder some methods for clarity * Small documentation fixes	2022-02-13 11:22:02 +01:00
Paul van Tilburg	9b9b1a5f77	Refactor so that no static is necessary for the maps cache * Replace the lazy `once_cell` by a maps handle type * Use Rocket's managed state to manage a handle * Ensure that the handlers have access to it * Pass another handle to the maps updater loop * Try to keep the lock as short as possible Still, long downloads block the lock. Add a FIXME to refactor this so the lock is only taken when updating the maps fields.	2022-02-12 21:35:58 +01:00
Paul van Tilburg	72fe9577bd	Implement retrieving and caching maps	2022-02-12 21:08:13 +01:00
Paul van Tilburg	d058ab4448	Set up a global maps (cache) object	2022-02-12 17:20:36 +01:00
