Don't use this class directly... its name may change in the future! Instead, ask Mail::Field for new instances based on the field name!
use Mail::Field; use MIME::Head;
# Create an instance from some text: $field = Mail::Field->new('Content-transfer-encoding', '7bit');
# Get the encoding. # Possible values: 'binary', '7bit', '8bit', 'quoted-printable', # 'base64' and '' (unspecified). Note that there can't be a # single default for this, since it depends on the content type! $encoding = $field->encoding;
