Enum FileStep 

pub enum FileStep {
    Range {
        offset: u64,
        len: usize,
    },
    Ready,
    Descriptor,
    Tensor,
    Composite,
}

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 one of the take_* methods — before the core produces another (ADR-041 § 4).

Variants

Range

Read the bytes at [offset, offset + len) into input_dst, then report how many arrived.

Filling fewer than len is normal — the remainder is requested again — but 0 means the file is shorter than its own index claims, which is a truncated file.

Fields

offset: u64

Absolute offset from the start of the file.

len: usize

Bytes still wanted at offset. Never 0.

Ready

The file is open and no job is in flight: call begin_descriptor, begin_tensor or begin_composite.

Descriptor

A descriptor is ready. Collect it with take_descriptor.

Tensor

A tensor is ready. Collect it with take_tensor.

Composite

A composite is ready. Collect it with take_composite.
