Expand description
An implicit converter: the given term, which must have type
(inner_ty) -> outer_ty, is used either in extractor or constructor
position as appropriate when a type mismatch with the given pair
of types would otherwise occur.
The “inner type”: the type to convert from, on the
right-hand side, or to, on the left-hand side. Must match
the singular argument type of the term.
The “outer type”: the type to convert to, on the right-hand
side, or from, on the left-hand side. Must match the ret_ty
of the term.
