Content

Constructors

ContentBuilder Builder (Maybe Int)	The content and optional content length.
ContentEnum (forall a. Enumerator Builder IO a)
ContentFile FilePath (Maybe FilePart)

Instances

IsString Content
HasReps ChooseRep
HasReps [(ContentType, Content)]
HasReps (ContentType, Content)

emptyContent :: Content Source

Zero-length enumerator.

class ToContent a whereSource

Anything which can be converted into Content. Most of the time, you will want to use the ContentBuilder constructor. An easier approach will be to use a pre-defined toContent function, such as converting your data into a lazy bytestring and then calling toContent on that.

Please note that the built-in instances for lazy data structures (String, lazy ByteString, lazy Text and Html) will not automatically include the content length for the ContentBuilder constructor.

Methods

toContent :: a -> Content Source

Instances

ToContent String
ToContent ByteString

Mime types

Data type

type ContentType = ByteString Source

typeHtml :: ContentType Source

typePlain :: ContentType Source

typeJson :: ContentType Source

typeXml :: ContentType Source

typeAtom :: ContentType Source

typeRss :: ContentType Source

typeJpeg :: ContentType Source

typePng :: ContentType Source

typeGif :: ContentType Source

typeJavascript :: ContentType Source

typeCss :: ContentType Source

typeFlv :: ContentType Source

typeOgv :: ContentType Source

Utilities

simpleContentType :: ContentType -> ContentType Source

Removes "extra" information at the end of a content type string. In particular, removes everything after the semicolon, if present.

For example, "text/html; charset=utf-8" is commonly used to specify the character encoding for HTML data. This function would return "text/html".

Representations

Arguments

= [ContentType]	list of content-types user accepts, ordered by preference

A function which gives targetted representations of content based on the content-types the user accepts.
