Query: Constant-roll inflation driven by holographic dark energy   The scenario of constant-roll inflation is investigated assuming that it is
caused by holographic dark energy with energy density $3M_p^2 c^2 / L^2$. The
energy density with varying $c$ parameter and Hubble radius as infrared cutoff
provides a proper description for the late time acceleration expansion. This
motivates us to study the role of the same holographic dark energy in the
scenario of constant-roll inflation. One of the main features of constant-roll
inflation is that the second slow-roll parameter is constant which is not
necessarily small. This feature brings a differential equation for the
parameter $c$. After finding an analytical solution for the parameter, the
observable parameters are obtained at the time of inflation, and by comparing
the model with data, the constants of the model are determined. The energy
scale of inflation is estimated which is about $10^{16} \; {\rm GeV}$. Finally,
a correspondence between the HDE and canonical scalar field is considered and
the behavior of the constructed potential and its magnitude is discussed.
