Synopsis

Content

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.

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.

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".

Evaluation strategy

newtype DontFullyEvaluate a Source #

Prevents a response body from being fully evaluated before sending the request.

Since 1.1.0
