Struct virtio_device::queue::Desc

pub struct Desc(pub DescType, pub DriverRange);

Reference to descriptor data.

Provides a higher level representation of a descriptors payload, compared to what ring::Desc::data reports. The conversion of a ring::Desc into a Desc necessitates some error checking and can fail with a DescError::BadRange.

Is provided as a DriverRange as the DescChain and its iterator have no way to translate a DriverRange and this responsibility is offloaded to the caller.

Tuple Fields

0: DescType

Trait Implementations

impl Clone for Desc

fn clone(&self) -> Desc

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Desc

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Desc

fn eq(&self, other: &Desc) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<Desc> for Desc

type Error = DescError

The type returned in the event of a conversion error.

fn try_from(desc: Desc) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Desc

impl StructuralPartialEq for Desc
