Struct rustc_arena::ArenaChunk

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

impl<T> ArenaChunk<T>

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

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.

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

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

Trait Implementations

impl<T> Drop for ArenaChunk<T>

fn drop(&mut self)

Executes the destructor for this type.

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.
