Description

Definition of a MediaBag object to hold binary resources, and an interface for interacting with it.

Synopsis

Documentation

data MediaBag Source #

A container for a collection of binary resources, with names and mime types. Note that a MediaBag is a Monoid, so mempty can be used for an empty MediaBag, and <> can be used to append two MediaBags.

lookupMedia :: FilePath -> MediaBag -> Maybe (MimeType, ByteString) Source #

Lookup a media item in a MediaBag, returning mime type and contents.

insertMedia Source #

Arguments

:: FilePath	relative path and canonical name of resource
-> Maybe MimeType	mime type (Nothing = determine from extension)
-> ByteString	contents of resource
-> MediaBag
-> MediaBag

Insert a media item into a MediaBag, replacing any existing value with the same name.

mediaDirectory :: MediaBag -> [(String, MimeType, Int)] Source #

Get a list of the file paths stored in a MediaBag, with their corresponding mime types and the lengths in bytes of the contents.
