Implementations

impl Chunk

pub const ZERO: Self = _

Chunk constant with zero address

pub fn iter_region<R: Region>(&self) -> RegionIterator<R>

Get an iterator for regions within this chunk.

Trait Implementations

impl Clone for Chunk

fn clone(&self) -> Chunk

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Chunk

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

Formats the value using the given formatter.

impl PartialEq for Chunk

fn eq(&self, other: &Chunk) -> 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 Chunk

fn partial_cmp(&self, other: &Chunk) -> 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 Region for Chunk

const LOG_BYTES: usize = 22usize

log2 of the size in bytes for the region.

fn from_aligned_address(address: Address) -> Self

Create a region from an address that is aligned to the region boundary. The method should panic if the address is not properly aligned to the region. For performance, this method should always be inlined.

fn start(&self) -> Address

Return the start address of the region. For performance, this method should always be inlined.

const BYTES: usize = _

The size in bytes for the region.

fn from_unaligned_address(address: Address) -> Self

Create a region from an arbitrary address.

fn align(address: Address) -> Address

Align the address to the region.

fn is_aligned(address: Address) -> bool

Check if an address is aligned to the region.

fn end(&self) -> Address

Return the end address of the region. Note that the end address is not in the region.

fn next(&self) -> Self

Return the next region after this one.

fn next_nth(&self, n: usize) -> Self

Return the next nth region after this one.

fn containing(object: ObjectReference) -> Self

Return the region that contains the object.

fn includes_address(&self, addr: Address) -> bool

Check if the given address is in the region.
