RowView.attachHeader

void attachHeader(const(HeaderIndex) * header) @safe pure nothrow @nogc

Attach a header index to this row to enable name-based field access.

The header index is not copied; only a pointer is stored. The caller is responsible for ensuring that the referenced HeaderIndex outlives this RowView usage. Typical usage is to build the header once from the first row and attach it to subsequent data rows.
