Implementations

impl TraceLayout

pub fn end_offset(&self) -> usize

pub fn validate( &self, stable_size: usize, metadata_start: usize, scratch_start: usize, ) -> bool

pub fn notification_offsets(&self, stable_home: usize) -> [usize; 2]

Two byte stores suffice: no read/modify/write in generated hot paths.

pub unsafe fn mark_home(&self, memory: *mut u8, home: usize)

Safety

memory must exclusively reference the complete writable state image.

pub unsafe fn mark_range(&self, memory: *mut u8, offset: usize, len: usize)

Mark host writes, including an element view into a larger array.

Safety

memory must exclusively reference the complete writable state image.

pub fn take(&self, memory: &mut [u8], groups: &mut Vec<usize>)

Consume only nonempty groups. Clock trigger clearing never touches this region. The caller owns the reusable result allocation.
