struct TableMemberVisitor

Visit all of the members in order, calling |func| with the previous member ordinal and the

current member ordinal. The main purpose of this function is to optimize closing unknown

envelopes in tables. The compiler can deterministically omit unknown envelope code paths if

it statically knows that there is no gap between two ordinals.

|func| should have the signature:

void func(

Member* member_ptr,

const fidl::internal::NaturalTableMember

<

...>

&

member_info,

std::integral_constant

<size

_t, PreviousOrdinal>,

std::integral_constant

<size

_t, CurrentOrdinal>,

);
