Encoding

newtype Encoding' tag

An encoding of a JSON value.

tag represents which kind of JSON the Encoding is encoding to, we reuse Text and Series as tags here.

Constructors

Encoding

Fields

• fromEncoding :: Builder

  Acquire the underlying bytestring builder.

Instances

Eq (Encoding' a)

Defined in Data.Aeson.Encoding.Internal

Methods

(==) :: Encoding' a -> Encoding' a -> Bool

(/=) :: Encoding' a -> Encoding' a -> Bool

Ord (Encoding' a)

Defined in Data.Aeson.Encoding.Internal

Methods

compare :: Encoding' a -> Encoding' a -> Ordering

(<) :: Encoding' a -> Encoding' a -> Bool

(<=) :: Encoding' a -> Encoding' a -> Bool

(>) :: Encoding' a -> Encoding' a -> Bool

(>=) :: Encoding' a -> Encoding' a -> Bool

max :: Encoding' a -> Encoding' a -> Encoding' a

min :: Encoding' a -> Encoding' a -> Encoding' a

Show (Encoding' a)

Defined in Data.Aeson.Encoding.Internal

Methods

showsPrec :: Int -> Encoding' a -> ShowS

show :: Encoding' a -> String

showList :: [Encoding' a] -> ShowS

type Encoding = Encoding' Value

Often used synonym for Encoding'.

encodingToLazyByteString :: Encoding' a -> ByteString

unsafeToEncoding :: Builder -> Encoding' a

Make Encoding from Builder.

Use with care! You have to make sure that the passed Builder is a valid JSON Encoding!

retagEncoding :: Encoding' a -> Encoding' b

data Series

A series of values that, when encoded, should be separated by commas. Since 0.11.0.0, the .= operator is overloaded to create either (Text, Value) or Series. You can use Series when encoding directly to a bytestring builder as in the following example:

toEncoding (Person name age) = pairs ("name" .= name <> "age" .= age)

Constructors

Empty

Defined in Data.Aeson.Types.ToJSON

Methods

(.=) :: ToJSON v => Text -> v -> Series
