Content
Constructors
| ContentBuilder !Builder !(Maybe Int) | The content and optional content length. |
| ContentSource !(Source (ResourceT IO) (Flush Builder)) | |
| ContentFile !FilePath !(Maybe FilePart) | |
| ContentDontEvaluate !Content |
Instances
| IsString Content | |
| ToContent Content | |
| ToTypedContent (ContentType, Content) | |
| ToContent (ContentType, Content) |
Zero-length enumerator.
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.

class ToFlushBuilder a whereSource

Mime types
Data type
type ContentType = ByteStringSource
Utilities
simpleContentType :: ContentType -> ContentTypeSource
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".
contentTypeTypes :: ContentType -> (ByteString, ByteString)Source
Evaluation strategy
newtype DontFullyEvaluate a Source
Prevents a response body from being fully evaluated before sending the request.
