Struct PartialOctetRead 

pub struct PartialOctetRead {
    pub data: Vec<u8>,
    pub eom_reason: EomReason,
}

The transfer an octet read completed before it failed — C’s *nbytesTransfered / *eomReason, which asynOctet::read writes out even when it returns a failing asynStatus (asynInterposeEos.c:242-253).

This owns the bytes rather than pointing at the caller’s buffer: it rides inside crate::error::AsynError::PartialRead, so the data and the status are one value and a ? on the read cannot deliver the failure while dropping the bytes. Every dispatch hop between the interpose and a record (port_actor → PortHandle → device support / SyncIO) hands the error on by value, so the transfer arrives with it.

Fields

data: Vec<u8>

The bytes transferred into the caller’s buffer before the failure.

eom_reason: EomReason

The end-of-message reason accumulated up to the failure.
