Struct entity_data::archetype::component::UnsafeVec

pub struct UnsafeVec(_);

Methods from Deref<Target = UnsafeCell<Vec<u8>>>

pub fn get(&self) -> *mut T

Gets a mutable pointer to the wrapped value.

This can be cast to a pointer of any kind. Ensure that the access is unique (no active references, mutable or not) when casting to &mut T, and ensure that there are no mutations or mutable aliases going on when casting to &T

Examples

use std::cell::UnsafeCell;

let uc = UnsafeCell::new(5);

let five = uc.get();

pub fn get_mut(&mut self) -> &mut T

Returns a mutable reference to the underlying data.

This call borrows the UnsafeCell mutably (at compile-time) which guarantees that we possess the only reference.

Examples

use std::cell::UnsafeCell;

let mut c = UnsafeCell::new(5);
*c.get_mut() += 1;

assert_eq!(*c.get_mut(), 6);

Trait Implementations

impl Default for UnsafeVec

fn default() -> UnsafeVec

Returns the “default value” for a type.

impl Deref for UnsafeVec

type Target = UnsafeCell<Vec<u8, Global>>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for UnsafeVec

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
