Struct FlatIndex 

pub struct FlatIndex { /* private fields */ }

Flat index using brute-force search.

Provides exact nearest neighbor results but O(n) per query.

Implementations

impl FlatIndex

pub fn new(config: IndexConfig) -> Self

Create a new flat index.

pub fn with_capacity(config: IndexConfig, capacity: usize) -> Self

Create with specified capacity.

pub const fn with_parallel(self, parallel: bool) -> Self

Enable/disable parallel search.

pub const fn with_parallel_threshold(self, threshold: usize) -> Self

Set parallel threshold.
