# Struct rustc_arena::ArenaChunk

source ·

    pub(crate) struct ArenaChunk<T = u8> {
        pub(crate) storage: NonNull<[MaybeUninit<T>]>,
        pub(crate) entries: usize,
    }

## Fields§

§`storage: NonNull<[MaybeUninit<T>]>`

The raw storage for the arena chunk.

§`entries: usize`

The number of valid entries in the chunk.

## Implementations§

source§

### impl<T> ArenaChunk<T>

source

#### pub(crate) unsafe fn new(capacity: usize) -> ArenaChunk<T>

source

#### pub(crate) unsafe fn destroy(&mut self, len: usize)

Destroys this arena chunk.

##### §Safety

The caller must ensure that `len` elements of this chunk have been initialized.

source

#### pub(crate) fn start(&mut self) -> *mut T

source

#### pub(crate) fn end(&mut self) -> *mut T

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
