[−][src]Enum mail::UseMediaType
Specifies how the content type should be handled when loading the data.
Depending on how the context implementation handles the loading it might already have a content type, but if not it might also need to "sniff" it, which can fail. Nevertheless how any of the aspects are handled in detail depends on the context implementation.
Variants
Auto
Sniff content type if no content type was given from any other place.
Default(MediaType)
Use this content type if no content type was given from any other place.
As resources are loaded by IRI they could be loaded from any place and this place could be storing the data with the right content type, in which case that content type should be used.
