Struct Arena

pub struct Arena<const SIZE: usize> { /* private fields */ }

A fixed size arena that can be used to allocate memory for arbitrary types.

Implementations

impl<'a, const SIZE: usize> Arena<SIZE>

pub const fn new() -> Self

Create a new arena with a fixed size buffer of SIZE bytes.

pub fn acquire_init_default<T: Init>(&'a self) -> Option<&'a T>

where T::InitArg: Default,

acquire a reference to a value of type T that can be initialized with the Init trait, using the default value of the InitArg. This is useful for types that require initialization and the init arg is Default.

pub fn acquire_init<T: Init>(&'a self, arg: T::InitArg) -> Option<&'a T>

acquire a reference to a value of type T that can be initialized with the Init trait, using a given InitArg. This is useful for types that require initialization.

pub fn acquire_default<T: Default>(&'a self) -> Option<&'a T>

acquire a reference to a value of type T that is initialized with it’s default value. This is useful for types that do not require initialization.

pub fn acquire<T>(&'a self, val: T) -> Option<&'a T>

acquire a reference to a value of type T that is initialized with the given value. This is useful for types that do not require initialization.

Trait Implementations

impl<const SIZE: usize> Default for Arena<SIZE>

fn default() -> Self

Returns the “default value” for a type.

impl<const SIZE: usize> Drop for Arena<SIZE>

fn drop(&mut self)

Executes the destructor for this type.

impl<const SIZE: usize> Send for Arena<SIZE>

impl<const SIZE: usize> Sync for Arena<SIZE>
