Struct virtio_device::mem::DriverRange

source ·
pub struct DriverRange(pub Range<usize>);
Expand description

Represents a range of memory as seen from the driver.

These ranges are only published by the driver and should never otherwise need to be created. The The only meaningful thing that can be done with them is to use the DriverMem::translate method to attempt to turn it into a DeviceRange.

Implementations§

source§

impl DriverRange

source

pub fn split_at(&self, offset: usize) -> Option<(Self, Self)>

Split the range at offset producing two new ranges.

Returns None if offset is not in the range, otherwise produces the two ranges [start.. start + offset) and [start + offset ..end).

source

pub fn len(&self) -> usize

impl From<Range<usize>> for DriverRange

source§

Converts to this type from the input type.
source§

impl PartialEq for DriverRange

source§

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

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

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.
