Struct heron::rapier_plugin::rapier::data::arena::Index

pub struct Index { /* fields omitted */ }

An index (and generation) into an Arena.

To get an Index, insert an element into an Arena, and the Index for that element will be returned.

Examples

use rapier::data::arena::Arena;

let mut arena = Arena::new();
let idx = arena.insert(123);
assert_eq!(arena[idx], 123);

Implementations

impl Index

pub fn from_raw_parts(a: usize, b: u64) -> Index

Create a new Index from its raw parts.

The parts must have been returned from an earlier call to into_raw_parts.

Providing arbitrary values will lead to malformed indices and ultimately panics.

pub fn into_raw_parts(self) -> (usize, u64)

Convert this Index into its raw parts.

This niche method is useful for converting an Index into another identifier type. Usually, you should prefer a newtype wrapper around Index like pub struct MyIdentifier(Index);. However, for external types whose definition you can't customize, but which you can construct instances of, this method can be useful.
