Struct WinNvmeDriver 

pub struct WinNvmeDriver {
    pub hardware_present: bool,
    /* private fields */
}

On Windows, raw NVMe Admin and NVM commands are sent via DeviceIoControl(IOCTL_STORAGE_QUERY_PROPERTY / IOCTL_STORAGE_PROTOCOL_COMMAND) against \\.\PhysicalDriveN. Requires Administrator privileges.

Falls back to MmapDriver automatically when:

• Not running as Administrator
• Running on a virtual disk (WSL2 .vhdx, Hyper-V)
• Physical drive has no NVMe ZNS capability

Fields

hardware_present: bool

Trait Implementations

impl StorageDriver for WinNvmeDriver

fn capabilities(&self) -> DriverCapabilities

fn write(&self, key: &str, data: &[u8]) -> Result<(), StorageError>

fn append(&self, key: &str, data: &[u8]) -> Result<(), StorageError>

fn read(&self, key: &str) -> Result<Vec<u8>, StorageError>

fn read_range( &self, key: &str, offset: usize, len: usize, ) -> Result<Vec<u8>, StorageError>

fn delete(&self, key: &str) -> Result<(), StorageError>

fn snapshot(&self, snapshot_id: &str) -> Result<(), StorageError>

Create a point-in-time snapshot named snapshot_id. On APFS this calls clonefile(2) and is O(1), zero-cost on disk.

fn flush(&self) -> Result<(), StorageError>

fn prefetch_hint(&self, _key: &str)

fn eviction_hint(&self, _key: &str)

fn describe(&self) -> &str
