Implementations

impl Line

pub const RESET_MARK_STATE: u8 = 1u8

pub const MAX_MARK_STATE: u8 = 127u8

pub const MARK_TABLE: SideMetadataSpec = crate::util::metadata::side_metadata::spec_defs::IX_LINE_MARK

Line mark table (side)

pub fn block(&self) -> Block

Get the block containing the line.

pub fn get_index_within_block(&self) -> usize

Get line index within its containing block.

pub fn mark(&self, state: u8)

Mark the line. This will update the side line mark table.

pub fn is_marked(&self, state: u8) -> bool

Test line mark state.

pub fn mark_lines_for_object<VM: VMBinding>( object: ObjectReference, state: u8 ) -> usize

Mark all lines the object is spanned to.

Trait Implementations

impl Clone for Line

fn clone(&self) -> Line

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Line

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

Formats the value using the given formatter.

impl PartialEq for Line

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

fn partial_cmp(&self, other: &Line) -> 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 Line

const LOG_BYTES: usize = 8usize

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.
