Struct BloomReadSet

Source

pub struct BloomReadSet { /* private fields */ }

👎Deprecated:

Unused; SSI lives in ssi/MvccManager. Scheduled for removal (Task 2 consolidation).

Expand description

Bloom filter for approximate read set

Uses k hash functions for O(k) operations with configurable false positive rate.

Implementations§

Source §

impl BloomReadSet

Source

pub fn new(expected_items: usize, false_positive_rate: f64) -> Self

👎Deprecated:

Unused; SSI lives in ssi/MvccManager. Scheduled for removal (Task 2 consolidation).

Create a new bloom filter

Size is calculated for target false positive rate: m = -n * ln(p) / (ln(2))^2 k = m/n * ln(2)

Source

pub fn add(&mut self, key: &[u8])

👎Deprecated:

Unused; SSI lives in ssi/MvccManager. Scheduled for removal (Task 2 consolidation).

Add a key to the read set

Source

pub fn might_contain(&self, key: &[u8]) -> bool

👎Deprecated:

Unused; SSI lives in ssi/MvccManager. Scheduled for removal (Task 2 consolidation).

Check if a key might be in the read set

Returns:

false: key is definitely NOT in set
true: key MIGHT be in set (or false positive)

Source

pub fn estimated_false_positive_rate(&self) -> f64

👎Deprecated:

Unused; SSI lives in ssi/MvccManager. Scheduled for removal (Task 2 consolidation).

Estimated false positive rate

Source

pub fn count(&self) -> usize

👎Deprecated:

Unused; SSI lives in ssi/MvccManager. Scheduled for removal (Task 2 consolidation).

Number of items added

Source

pub fn memory_bytes(&self) -> usize

👎Deprecated:

Unused; SSI lives in ssi/MvccManager. Scheduled for removal (Task 2 consolidation).

Memory usage in bytes
