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>
impl<T> ArenaChunk<T>
pub(crate) unsafe fn new(capacity: usize) -> ArenaChunk<T>
sourcepub(crate) unsafe fn destroy(&mut self, len: usize)
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

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
