Struct cranelift_entity::ListPool

source ·
pub struct ListPool<T: EntityRef + ReservedValue> { /* private fields */ }
Expand description

A memory pool for storing lists of T.

Implementations§

source§

impl<T: EntityRef + ReservedValue> ListPool<T>

source

pub fn new() -> Self

Create a new list pool.

source

pub fn with_capacity(len: usize) -> Self

Create a new list pool with the given capacity for data pre-allocated.

source

pub fn capacity(&self) -> usize

Get the capacity of this pool. This will be somewhat higher than the total length of lists that can be stored without reallocating, because of internal metadata overheads. It is mostly useful to allow another pool to be allocated that is likely to hold data transferred from this one without the need to grow.

source

pub fn clear(&mut self)

Clear the pool, forgetting about all lists that use it.

This invalidates any existing entity lists that used this pool to allocate memory.

The pool’s memory is not released to the operating system, but kept around for faster allocation in the future.

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.
