Enum devices::virtio::descriptor_chain::DescriptorAccess

pub enum DescriptorAccess {
    DeviceRead,
    DeviceWrite,
}

Type of access allowed for a single virtio descriptor within a descriptor chain.

Variants

DeviceRead

Descriptor is readable by the device (written by the driver before putting the descriptor chain on the available queue).

DeviceWrite

Descriptor is writable by the device (read by the driver after the device puts the descriptor chain on the used queue).

Trait Implementations

impl Clone for DescriptorAccess

fn clone(&self) -> DescriptorAccess

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DescriptorAccess

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

Formats the value using the given formatter.

impl PartialEq for DescriptorAccess

fn eq(&self, other: &DescriptorAccess) -> 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.
