Trait ringbuf::ring_buffer::Container

pub unsafe trait Container<T> {
    type Internal;

    // Required methods
    fn into_internal(self) -> Self::Internal;
    unsafe fn from_internal(this: Self::Internal) -> Self;
    fn as_mut_ptr(this: &Self::Internal) -> *mut MaybeUninit<T>;
    fn len(this: &Self::Internal) -> usize;
}

Abstract container for the ring buffer.

Container items must be stored as a contiguous array.

Safety

Self::len/[Self::is_empty] must always return the same value.

Container must not cause data race on concurrent [Self::as_mut_slice]/Self::as_mut_ptr calls.

Required Associated Types

type Internal

Internal representation of the container.

Must not be aliased with its content.

Required Methods

fn into_internal(self) -> Self::Internal

Transform container to internal representation.

unsafe fn from_internal(this: Self::Internal) -> Self

Restore container from internal representation.

Safety

this must be valid.

fn as_mut_ptr(this: &Self::Internal) -> *mut MaybeUninit<T>

Return pointer to the beginning of the container items.

fn len(this: &Self::Internal) -> usize

Length of the container.
