Enum WriteStep 

pub enum WriteStep {
    Output {
        len: usize,
    },
    ItemWritten,
}

What the core has for its driver.

One request outstanding at a time, answered with report_written (ADR-041 § 4).

Variants

Output

Write output_src — len bytes — then report how many the sink accepted. Fewer is normal; 0 is never progress.

Fields

len: usize

Bytes remaining for the current slice. Never 0.

ItemWritten

Every byte of the submitted item is written. The borrowed payloads are released: the core holds no pointer into them from here on (ADR-041 § 3).
