Synopsis

Encoding

newtype Encoding' tag Source #

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.

type Encoding = Encoding' Value Source #

Often used synonym for Encoding'.

unsafeToEncoding :: Builder -> Encoding' a Source #

Make Encoding from Builder.

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

data Series Source #

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)
