`slices::Slices::get_range` was too closely following the example of
`http_serve::Entity::get_range`:
The latter is once-per-request, so just boxing is low-cost and makes
sense to easily avoid monomorphization bloat when there are potentially
many types of entity streams in one program. In Moonfire, it's used with
different streams defined in the `moonfire_nvr::web::mp4`,
`moonfire_nvr::bundled_ui`, and `http_serve::file` modules. Putting them
all into a single boxless enum would be a pain. In particular, the last
one is not a nameable type today and would need more generic parameters
to implement the caller-demanded `Entity` definition.
The former is once-per-slice, there are tons of slices per request, and
it's easy to define a two-case enum right where it's needed. So the
trade-off is quite different.
Also fix up some out-of-date comments.
I think this is a big improvement in readability.
I removed the `lnav` config, which is a little sad, but I don't think it
supports this structured logging format well. Still seems worthwhile on
balance.
I'm tired of all the boilerplate, so use the new
GPL-3.0-linking-exception license identifier instead in all the server
components.
I left the ui stuff alone because I'm just going to replace it (#111).
Add a checker for the header because it's easy to forget.
I want to make the project more accessible by not expecting folks to
match my idiosyncratic style. Now almost [1] everything is written
in the "standard" style. CI enforces this.
[1] "Almost": I used #[rustfmt::skip] in a few sections where I felt
aligning things in columns significantly improves readability.
Besides being more clear about what belongs to which, this helps with
docker caching. The server and ui parts are only rebuilt when their
respective subdirectories change.
Extend this a bit further by making the webpack build not depend on
the target architecture. And adding cache dirs so parts of the server
and ui build process can be reused when layer-wide caching fails.
