fields IEnumerable<TField>

representing the fields selected to form the mask

toOrigin Func<TField, Expression<Func<TOrigin, object?>>>

Function that gives the expression to convert the TField to a member of TOrigin

toDest Func<TField, Expression<Func<TDest, object?>>>

Function that gives the expression to convert the TField to a member of TDest

assignments IEnumerable<MemberAssignment>?

Additional assignments to perform when building TDest
