|

### Added
|
||||
|
||||
* Add `.set_content_type()` and `.set_content_disposition()` methods
|
||||
to `fs::NamedFile` to allow overriding the values inferred by default
|
||||
|
||||
* Add `fs::file_extension_to_mime()` helper function to get the MIME
|
||||
type for a file extension
|
||||
|
||||
* Add `.content_disposition()` method to parse Content-Disposition of
|
||||
multipart fields
