Struct OptimisticVersion 

Source 
pub struct OptimisticVersion { /* private fields */ }
Expand description

Optimistic concurrency control for HNSW nodes Uses version counters instead of locks for wait-free reads

Implementations§

Source§

impl OptimisticVersion

Source

pub fn new() -> Self

Source

pub fn read_version(&self) -> u64

Read the version (for optimistic read)

Source

pub fn is_stable(&self, version: u64) -> bool

Check if version is stable (not being modified)

Source

pub fn validate(&self, read_version: u64) -> bool

Validate that version hasn’t changed

Source

pub fn try_write_begin(&self) -> Option<WriteGuard<'_>>

Try to begin a write (returns None if concurrent write in progress)
