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
