Data.OpenApi.Internal.ParamSchema

Synopsis

Documentation

binarySchema :: Schema Source #

Default schema for binary data (any sequence of octets).

byteSchema :: Schema Source #

Default schema for binary data (base64 encoded).

passwordSchema :: Schema Source #

Default schema for password string. "password" format is used to hint UIs the input needs to be obscured.

class ToParamSchema a where Source #

Convert a type into a plain Schema.

In previous versions of the package there was a separate type called ParamSchema, which was included in a greater Schema. Now this is a single class, but distinction for schema generators for "simple" types is preserved.

ToParamSchema is suited only for primitive-like types without nested fields and such.

An example type and instance:

{-# LANGUAGE OverloadedStrings #-}   -- allows to write Text literals

import Control.Lens

data Direction = Up | Down

instance ToParamSchema Direction where
  toParamSchema _ = mempty
     & type_ ?~ OpenApiString
     & enum_ ?~ [ "Up", "Down" ]

Instead of manually writing your ToParamSchema instance you can use a default generic implementation of toParamSchema.

To do that, simply add deriving FPFormat clause to your datatype and declare a ToParamSchema instance for your datatype without giving definition for toParamSchema.

For instance, the previous example can be simplified into this:

{-# LANGUAGE DeriveGeneric #-}

import GHC.Generics (Generic)

data Direction = Up | Down deriving Generic

instance ToParamSchema Direction

Minimal complete definition

Nothing

Methods

toParamSchema :: Proxy a -> Schema Source #

Convert a type into a plain parameter schema.

>>> BSL.putStrLn $ encodePretty $ toParamSchema (Proxy :: Proxy Integer)
{
    "type": "integer"
}
