Struct ncollide_utils::data::uid_remap::FastKey

pub struct FastKey { /* fields omitted */ }

A special type of key used by UidRemap to perform faster lookups than with the user-defined id of type usize.

Methods

impl FastKey

pub fn new_invalid() -> FastKey

Creates a new invalid key that won't be used by the UidRemap structure, ever.

pub fn uid(&self) -> usize

The small uid contained by this key.
