Struct resources::AddressRange

pub struct AddressRange {
    pub start: u64,
    pub end: u64,
}

Represents a range of addresses from start to end, inclusive.

Why not use the standard RangeInclusive? RangeInclusive is not Copy, because it tries to be an iterator as well as a range (which also means it is larger than necessary). Additionally, we would also like to implement some convenience functions for our own type.

Fields

start: u64

end: u64

Implementations

impl AddressRange

pub const fn from_start_and_end(start: u64, end: u64) -> Self

Creates a new AddressRange from start and end (inclusive) addresses.

pub const fn from_start_and_size(start: u64, size: u64) -> Option<Self>

Creates a new AddressRange from start extending size bytes.

Returns None if the generated range is not representable as an AddressRange.

pub const fn empty() -> Self

Returns an empty range.

pub fn is_empty(&self) -> bool

Returns true if this range is empty (contains no addresses).

pub fn contains(&self, address: u64) -> bool

Returns true if this range contains address.

pub fn contains_range(&self, other: AddressRange) -> bool

Returns true if other is fully contained within this range.

Empty ranges are considered to be not contained by any range.

pub fn overlaps(&self, other: AddressRange) -> bool

Returns true if the two ranges have any addresses in common.

pub fn intersect(&self, other: AddressRange) -> AddressRange

Find the intersection (overlapping region) of two ranges.

If there is no intersection, the resulting AddressRange will be empty.

pub fn non_overlapping_ranges( &self, other: AddressRange ) -> (AddressRange, AddressRange)

Returns the ranges of addresses contained in self but not in other.

The first returned range will contain the addresses in self that are less than the start of other, which will be empty if the starts of the ranges coincide.

The second returned range will contain the addresses in self that are greater than the end of other, which will be empty if the ends of the ranges coincide.

pub fn split_at(&self, split_start: u64) -> (AddressRange, AddressRange)

Returns the two subsets of this range split at the split_start address.

If split_start is not contained in this range, returns the original range and an empty range.

pub fn len(&self) -> Option<u64>

Computes the length of an AddressRange.

Returns None if the length cannot be represented in u64 (if the range is 0..=u64::MAX).

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

Trait Implementations

impl Clone for AddressRange

fn clone(&self) -> AddressRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AddressRange

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AddressRange

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for AddressRange

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

Formats the value using the given formatter.

impl From<AddressRange> for RangeInclusive<u64>

fn from(address_range: AddressRange) -> RangeInclusive<u64>

Converts to this type from the input type.

impl From<RangeInclusive<u64>> for AddressRange

fn from(range: RangeInclusive<u64>) -> AddressRange

Converts to this type from the input type.

impl Ord for AddressRange

Custom comparison function that provides a total order over all possible AddressRange values and considers all empty ranges to be equal.

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for AddressRange

fn eq(&self, other: &Self) -> 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 PartialOrd for AddressRange

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

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for AddressRange

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for AddressRange
