@subsection Trivial distance
@table @asis
@item @emph{Name:}
trivial
@item @emph{Type:}
@code{CASS_VEC_DIST_TYPE_TRIVIAL}
@item @emph{Vector type:}
@code{CASS_ANY}
@item @emph{Parameters:}
(none)
@item @emph{Description:}
The trivial distance measure always return 0 for any pair of vecsets.  This
vecset distance is only for debugging purpose.

@subsection Cosine distance
@table @asis
@item @emph{Name:}
cosine
@item @emph{Type:}
@code{CASS_VEC_DIST_TYPE_COS}
@item @emph{Vector type:}
@code{CASS_VEC_FLOAT}
@item @emph{Parameters:}
(none)
@item @emph{Description:}
This is actually the dot product of two vectors.  If the vectors are not unit
vectors, then it's actually not the cosine distance.
