Faviconduit.get(uri)

Takes a url and attempts to returns the favicon object. The url can be fairly loosely specified because Addressable::URI.heuristic_parse is used to figure it out.

obj.url

The favicon url it was ultimately found at.

obj.data

The favicon image data.

Faviconduit::MissingFavicon

Raises this if the favicon simply isn’t found.

Faviconduit::InvalidFavicon

Raises this if the favicon is determined to be not a valid favicon. Currently (0.1) determins this if the content-type is not /^image/ or the size is 0 bytes.

Faviconduit::Error

This is the parent of all faviconduit exceptions and can be caught instead of the more specific exceptions.
