Struct IntVecPool 

pub struct IntVecPool { /* private fields */ }

Spare Vec<i32> buffers for element paths and object chains, which the VM makes and drops for every property access: reusing them saves an allocation and a free each time (a tenth of the VM’s frame time in particle scripts, more with the console allocators).

Implementations

impl IntVecPool

pub fn take(&mut self) -> Vec<i32>

An empty vector, reused when one is spare.

pub fn take_copy(&mut self, items: &[i32]) -> Vec<i32>

A copy of items in a reused vector.

pub fn give(&mut self, v: Vec<i32>)

Keeps v for reuse (small ones, a few at a time).

Trait Implementations

impl Clone for IntVecPool

fn clone(&self) -> Self

Spare buffers are not state: a copy starts without them.

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

Performs copy-assignment from source.

impl Debug for IntVecPool

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

Formats the value using the given formatter.

impl Default for IntVecPool

fn default() -> IntVecPool

Returns the “default value” for a type.
