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.

Mime types

Data type

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.
