Struct MembershipFilter 

pub struct MembershipFilter { /* private fields */ }

Membership filter backed by a dense bitmap.

Implementations

impl MembershipFilter

pub fn new_include(vector_count: u64) -> Self

Create a new include-mode filter with given capacity. All bits start clear.

pub fn new_exclude(vector_count: u64) -> Self

Create a new exclude-mode filter with given capacity. All bits start clear.

pub fn add(&mut self, vector_id: u64)

Add a vector ID to the filter.

pub fn remove(&mut self, vector_id: u64)

Remove a vector ID from the filter.

pub fn contains(&self, vector_id: u64) -> bool

Check if a vector ID is visible through this filter.

In Include mode: visible iff the bit is set. In Exclude mode: visible iff the bit is NOT set.

pub fn member_count(&self) -> u64

Number of set bits (members in the bitmap).

pub fn vector_count(&self) -> u64

Total vector capacity.

pub fn mode(&self) -> FilterMode

Filter mode.

pub fn generation_id(&self) -> u32

Generation ID.

pub fn bump_generation(&mut self)

Increment generation ID.

pub fn serialize(&self) -> Vec<u8>

Serialize the bitmap to bytes (just the raw bitmap words).

pub fn deserialize( data: &[u8], header: &MembershipHeader, ) -> Result<Self, RvfError>

Deserialize a MembershipFilter from bitmap bytes and a header.

pub fn to_header(&self) -> MembershipHeader

Build a MembershipHeader for this filter.
