Enum ReadStep 

pub enum ReadStep {
    Input {
        len: usize,
    },
    Tensor,
    Finished,
}

What the core needs next from its driver.

Exactly one request is outstanding at a time, and the driver answers it — with report_filled or take_tensor — before the core produces another (ADR-041 § 4).

Variants

Input

Fill up to len bytes of input_dst, then report how many arrived. Filling fewer is normal; 0 means end of input.

Fields

len: usize

Bytes remaining for the current target. Never 0.

Tensor

A tensor is complete. Collect it with take_tensor.

Finished

End of input, reached cleanly at a tensor boundary.
