* Evaluate NoContent before rendering it, so it shows up as covered in coverage reports
* failing test as well
* test that NoContent gets rendered if it is not an exception

As the head method isn't allowed to contain any response body, no
general Head Verb is added. (This may easily lead to wrong usages...)

Move `HasServer (NamedRoutes routes)` instance
The instance has been moved to `Servant.Server.Internal`, as the
instances for other combinators. It is necessary so that the instance
can be re-exported from `Servant.Server` without circular imports.
Otherwise, users have to import `Servant.Server.Generic` manually ;
forgetting to do so will produce confusing error messages about the
missing instance.
Move `HasClient (NamedRoutes routes)` instance
Moved so that the instance is made available when importing
`Servant.Client`, avoiding possibly confusing errors when
`Servant.Client.Generic` isn't imported.
Allows users to directly embed APIs defined as records of routes into
vanilla Servant API types.
E.g.:
```haskell
data MyRoutes mode = MyRoutes
{ version :: mode :- Get '[JSON] Int
, …
}
type API = "prefix" :> NamedRoutes MyRoutes :<|> …
```
APIs can thus be recursively defined directly with Generic record types.
We do not need the `ToJSON` instance for `WithStatus`
it would cause an overlap between:
```
ToJSON a => MimeRender JSON a
```
and
```
forall cty a. MimeRendercty a => MimeRender cty (WithStatus a)
```
and Servant just needs the `MimeRender` typeclass for it to work
* Add some more docs to the UVerb module
* cookbook/uverb: Change GHC versions
CI was complaining some version did not exist. Trying to bump
Also added 8.10.1
* doc/cookbook/uverb: Remove 8.4.4 from tested versions
CI was running into a cabal bug for some reason
Currently there is no way for Servant users to customize formatting of
error messages that arise when combinators can't parse URL or request
body, apart from reimplementing those combinators for themselves or
using middlewares.
This commit adds a possibility to specify custom error formatters
through Context.
Fixes#685
- Rename GenResponse to ResponseF (analogous to RequestF)
- add NFData Headers
- Make Request and Response bodies be SourceIO,
i.e. move conversions into specific implementations
- Introduce SourceT, which is simple variant of "correct `ListT`".
There are another variants possible (like in `streaming`),
but I'm not sure there's much real difference.
- Introduce `Codensity`. There's a flag if people don't want to depend
on `kan-extensions`.
- `StreamGenerator` and `ResultStream` are both `SourceT`.
`Stream` combinator in `servant-client` uses `Codensity` for CPS.
- Add servant-machines, servant-conduit, servant-pipes
- Add streaming cookbook: just code, no explanations.
- Add a script to run streaming 'benchmarks'
- Add Streaming endpoint to the comprehensive API.
- Rename BuildFromStream to FromResultStram
- I'm tempted to rename everything in the Servant.API.Stream
(add some prefixes, `header` is too good name to steal)
The TODO in `servant-docs` is left intentionally.
