Struct BloomPointer 

pub struct BloomPointer<T> { /* private fields */ }

(Bloom64, Arc<T>) - 16 bytes on 64-bit.

Implementations

impl<T> BloomPointer<T>

pub const SIGNATURE: AxisMask

Direction signature of BloomPointer<T>. Engages the K_content_prefix axis (bloom-filter summary of the target’s keys stored at slot for fast set-membership rejection before deref).

pub fn new(target: Arc<T>, bloom: Bloom64) -> Self

pub fn from_keys<K, I>(target: Arc<T>, keys: I) -> Self

where K: Hash, I: IntoIterator<Item = K>,

Build the bloom from a key iterator. Caller is responsible for providing the keys (typically by walking target and yielding owned key copies or references).

pub fn bloom(&self) -> Bloom64

pub fn target(&self) -> &Arc<T>

pub fn might_contain<K: Hash + ?Sized>(&self, key: &K) -> bool

Skip-the-deref membership test. Returns false for definitely-no, true for might-be-yes.

pub fn set_bloom(&mut self, b: Bloom64)

Replace the bloom after target mutation. Caller is responsible for ensuring the new bloom reflects current contents.
