Struct AhciBlockDevice 

pub struct AhciBlockDevice { /* private fields */ }

Wrapper around an AhciPort for the BlockDevice trait.

In a production system, this would hold references to DMA-allocated command list and received FIS areas. For now, it provides the structural interface.

Implementations

impl AhciBlockDevice

pub fn new(port: AhciPort, name: String) -> Self

Create a new AHCI block device from a port.

pub fn port(&self) -> &AhciPort

Get a reference to the underlying port.
