Interface: DrawTarget ​

Defined in: packages/core/src/render/types.ts:315

The receiving side of draw commands — everything a series knows about the renderer. Requiring this interface instead of a concrete renderer means a series doesn't know how commands pile up or when they get replayed.

Methods ​

drawCustom()? ​

optional drawCustom(draw): void

Defined in: packages/core/src/render/types.ts:328

An extension sends its own primitive. It's optional so existing implementations don't break.

Don't call this directly — use drawCustom(target, draw), which replays the fallback on a surface missing this method. Calling this directly lets optional chaining quietly fall to drawing nothing.
