Production / Limits and defaults On this page Production / Limits and defaults
Limits and defaults Copy as Markdown Every bound and default of TinyStore in one place, by engine. A call past a
bound fails with a limit or invalid error that names the bound, and
changes nothing. Each chapter of the book has the same numbers beside the
calls they bound.
