Struct rstar::DefaultParams

pub struct DefaultParams;

The default parameters used when creating an r-tree without specific parameters.

Trait Implementations

impl Clone for DefaultParams

fn clone(&self) -> DefaultParams

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<DefaultParams> for DefaultParams

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl RTreeParams for DefaultParams

const MIN_SIZE: usize = 3usize

The minimum size of an internal node. Must be at most half as large as MAX_SIZE. Choosing a value around one half or one third of MAX_SIZE is recommended. Higher values should yield slightly better tree quality while lower values may benefit insertion performance.

const MAX_SIZE: usize = 6usize

The maximum size of an internal node. Larger values will improve insertion performance but increase the average query time.

const REINSERTION_COUNT: usize = 2usize

The number of nodes that the insertion strategy tries to occasionally reinsert to maintain a good tree quality. Must be smaller than MAX_SIZE - MIN_SIZE. Larger values will improve query times but increase insertion time.

type DefaultInsertionStrategy = RStarInsertionStrategy

The insertion strategy which is used when calling RTree::insert.
