Struct KvRing 

pub struct KvRing { /* private fields */ }

Implementations

impl KvRing

pub fn new(rows: usize, window: usize) -> KvRing

pub fn rows(&self) -> usize

pub fn base(&self) -> usize

pub fn window(&self) -> usize

pub fn append_plan( &self, len: usize, retain_from: usize, append_rows: usize, ) -> Result<KvRingAppend, String>

Plan a contiguous physical append. When the tail would wrap, retain the caller’s exact aligned read prefix at row zero; the following read remains one contiguous CUDA view.

pub fn apply_rebase(&mut self, new_base: usize)

pub fn physical_range( &self, start: usize, end: usize, ) -> Result<Range<usize>, String>

pub fn can_rewind_to(&self, len: usize) -> bool

A rewind is usable only when the next aligned Step35 window view is still resident.
