def FloatArray.markLinear (ds : FloatArray) : FloatArray

Marks a float array as linear, which is a no-op logically.

At runtime the array is first made unique, copying it if the reference is not already unique, and then marked. If the environment variable LEAN_ABORT_ON_NONLINEAR is set, every non-linear use from that point on causes a panic instead of a silent copy.

To debug where the non-linearity is coming from you can set a breakpoint on lean_internal_panic.

def FloatArray.propagateMark (ds : FloatArray) (es : FloatArray) : FloatArray

Returns es, propagating the linearity marker of ds onto it. This is a no-op logically.

unsafe def FloatArray.forInUnsafe {β : Type v} {m : Type v → Type w} [Monad m] (as : FloatArray) (b : β) (f : Float → β → m (ForInStep β)) : m β

We claim this unsafe implementation is correct because an array cannot have more than usizeSz elements in our runtime. This is similar to the Array version.
