  The generic digraph $(D,E)$ is the unique countable homogeneous digraph that
embeds all finite digraphs. In this paper, we determine the lattice of reducts
of $(D,E)$, where a structure $\mathcal{M}$ is a reduct of $(D,E)$ if it has
domain $D$ and all its $\emptyset$-definable relations are
$\emptyset$-definable relations of $(D,E)$. As $(D,E)$ is
$\aleph_0$-categorical, this is equivalent to determining the lattice of closed
groups that lie in between Aut$(D,E)$ and Sym$(D)$.
