FIXTURE_DATA(9)

🎀 NAME 🎀

FIXTURE_DATA — and yes bestie, this is FIXTURE_DATA(9) from the Kernel API Manual 💖 — wraps the struct name so we have one less argument to pass around. That's the whole serve, no cap.

✨ SYNOPSIS ✨

FIXTURE_DATA (datatype_name );

🌸 ARGUMENTS 🌸

• datatype_name — datatype name. That's it, that's the argument 🎀

💅 DESCRIPTION 💅

FIXTURE_DATA(datatype_name)

Okay so almost always, you want just FIXTURE instead (see below). This call may be used when the type of the fixture data is needed. In general, this should not be needed unless the *self* is being passed to a helper directly.
