Struct Descriptor 

pub struct Descriptor { /* private fields */ }

One address-free split-ring descriptor used by the in-memory model.

Implementations

impl Descriptor

pub fn readable(bytes: Vec<u8>) -> Self

Construct one mapped device-readable descriptor.

pub fn writable(bytes: Vec<u8>) -> Self

Construct one mapped device-writable descriptor.

pub fn raw(bytes: Vec<u8>, flags: u16, next: u16) -> Self

Construct a mapped descriptor with raw split-ring flags and a local next index.

pub const fn unmapped(bytes: u64, flags: u16, next: u16) -> Self

Construct an unmapped descriptor for deterministic addressability tests.

pub fn len(&self) -> u64

Descriptor length.

pub fn is_empty(&self) -> bool

Whether this descriptor has zero length.

pub const fn flags(&self) -> u16

Raw split-ring flags.

pub const fn next(&self) -> u16

Local next index used by DriverChain::raw.
