Struct YogApi 

#[repr(C)]
pub struct YogApi {
    pub abi_version: u32,
    pub size: u32,
    pub bus: *const YogBus,
    pub gfx: unsafe extern "C" fn() -> *const YogGfxApi,
}

Stable C ABI — re-exported so mods don’t need a direct yog-abi dependency. Passed to yog_mod_register: the bus — everything a mod does goes through it (docs/design/bus.md) — and the one thing that can’t afford a message, the frame’s graphics.

When mods compiled against ABI N load on a runtime with ABI M > N: fields beyond size are not present in the mod’s view — check size before accessing fields added in later minor versions.

Fields

abi_version: u32

size: u32

sizeof(YogApi) at the runtime’s build time.

bus: *const YogBus

The bus: calls, events and services by address (docs/design/bus.md). Valid for the runtime’s lifetime.

gfx: unsafe extern "C" fn() -> *const YogGfxApi

The frame’s graphics while a render event (yog:event/client/render/…) runs on this thread; null otherwise. Valid until the event’s handlers return.
