Taking the address of a variable
x
via&(mut) x
neither reads nor writes the variable, so the access tox
should neither be aVariableReadAccess
nor aVariableWriteAccess
. This also includes implicit references in compound assignmentsx += y
which really means(&mut x).add_assign(y)
.Note that once we implement SSA support, then (some) variable references will be modeled as uncertain variable writes.
