emptyContent :: Content Source #
Zero-length enumerator.
class ToContent a where Source #
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.
Instances
class ToFlushBuilder a where Source #
A class for all data which can be sent in a streaming response. Note that for textual data, instances must use UTF-8 encoding.
Since 1.2.0
Methods
toFlushBuilder :: a -> Flush Builder Source #

Mime types
Data type
type ContentType = ByteString 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".
contentTypeTypes :: ContentType -> (ByteString, ByteString) Source #
Give just the media types as a pair.
For example, "text/html; charset=utf-8" returns ("text", "html")
Evaluation strategy
newtype DontFullyEvaluate a Source #
Prevents a response body from being fully evaluated before sending the request.
Since 1.1.0
