Struct FlatIndex 

pub struct FlatIndex {
    pub entries: Vec<VectorEntry>,
    pub dims: usize,
}

A flat in-memory ANN index holding a collection of VectorEntry values.

All entries in the index must have the same dimensionality.

Fields

entries: Vec<VectorEntry>

All stored entries.

dims: usize

Dimensionality of the vectors stored in this index.

Implementations

impl FlatIndex

pub fn new(dims: usize) -> Self

Create an empty flat index for vectors of the given dimensionality.

pub fn insert(&mut self, entry: VectorEntry) -> Result<(), MergeError>

Insert an entry. Returns an error if the entry’s vector length does not match the index dimensionality.

pub fn len(&self) -> usize

Number of entries in the index.

pub fn is_empty(&self) -> bool

Returns true if the index contains no entries.

Trait Implementations

impl Clone for FlatIndex

fn clone(&self) -> FlatIndex

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FlatIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FlatIndex

fn eq(&self, other: &FlatIndex) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
