Synopsis

data HpackError
formatHpackError :: ProgramName -> HpackError -> String
newtype ProgramName = ProgramName {
- unProgramName :: String
}
type URL = String
data Status = Status {
- statusCode :: Int
- statusMessage :: ByteString
}
formatStatus :: Status -> String

Documentation

NOTE: This module is exposed to allow integration of Hpack into other tools. It is not meant for general use by end users. The following caveats apply:

The API is undocumented, consult the source instead.
The exposed types and functions primarily serve Hpack's own needs, not that of a public API. Breaking changes can happen as Hpack evolves.

As an Hpack user you either want to use the hpack executable or a build tool that supports Hpack (e.g. stack or cabal2nix).

data Status #

HTTP Status.

Only the statusCode is used for comparisons.

Please use mkStatus to create status codes from code and message, or the Enum instance or the status code constants (like ok200). There might be additional record members in the future.

Note that the Show instance is only for debugging.
