Struct Range 

pub struct Range { /* private fields */ }

A physical memory range type.

Range specifies a half open iterval of physical memory [addr, addr + size) with ty describing the usage of this memory. It layout-compatible to zbi_mem_range_t, but with the benefit of being able to use allocated types.

addr + size never overflows.

Implementations

impl Range

pub const fn new(addr: u64, size: u64, ty: Type) -> Self

Construct a new range.

If addr + size > u64::MAX, the size is reduced so there is no overflow.

pub fn slice_from_zbi_mem_ranges(ranges: &mut [MemRange]) -> &mut [Self]

Sanitize a mutable slice of zbi::MemRange in-place and view it as &mut [Range].

pub const fn addr(&self) -> u64

The start address of the range.

pub const fn size(&self) -> u64

The size of the range.

pub const fn ty(&self) -> Type

The type of the range.

pub const fn end(&self) -> u64

The exclusive endpoint of the range.

pub const fn align_out(&self, alignment: u64) -> Self

Align the ends of a range outward to be multiples of alignment.

The start address is rounded down and the end address is rounded up. If the end address would be larger than 2^64, we saturate it.

Panics

Panics if alignment is not a power of two.

pub const fn intersects(&self, other: &Range) -> bool

Determine if other intersects with self.

Intersection is type-agnostic.

Trait Implementations

impl Clone for Range

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Range

impl Debug for Range

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

Formats the value using the given formatter.

impl Eq for Range

impl PartialEq for Range

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Range

fn partial_cmp(&self, other: &Range) -> Option<Ordering>

Order ranges lexicographically.

Comparisons are not type sensitive unless both the start address and size are equal to each other, in which case different types yields a None.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
