Struct DriverRange

pub struct DriverRange(pub Range<usize>);

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

impl DriverRange

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).

pub fn len(&self) -> usize

Trait Implementations

impl Clone for DriverRange

fn clone(&self) -> DriverRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DriverRange

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

Formats the value using the given formatter.

impl From<Range<usize>> for DriverRange

fn from(range: Range<usize>) -> Self

Converts to this type from the input type.

impl PartialEq for DriverRange

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<(u64, u32)> for DriverRange

type Error = ()

The type returned in the event of a conversion error.

fn try_from(range: (u64, u32)) -> Result<Self, Self::Error>

Performs the conversion.
