Struct slice_ring_buffer::Buffer

pub struct Buffer<T> { /* private fields */ }

Mirrored memory buffer of length len.

The buffer elements in range [0, len/2) are mirrored into the range [len/2, len).

Implementations

impl<T> Buffer<T>

pub fn len(&self) -> usize

Number of elements in the buffer.

pub fn is_empty(&self) -> bool

Is the buffer empty?

pub unsafe fn ptr(&self) -> *mut T

Pointer to the first element in the buffer.

pub unsafe fn as_slice(&self) -> &[T]

Interprets contents as a slice.

Warning: Some memory might be uninitialized.

pub unsafe fn as_mut_slice(&mut self) -> &mut [T]

Interprets contents as a mut slice.

Warning: Some memory might be uninitialized.

pub unsafe fn get(&self, i: usize) -> &T

Interprets content as a slice and access the i-th element.

Warning: The memory of the i-th element might be uninitialized.

pub unsafe fn get_mut(&mut self, i: usize) -> &mut T

Interprets content as a mut slice and access the i-th element.

Warning: The memory of the i-th element might be uninitialized.

pub fn new() -> Self

Creates a new empty Buffer.

pub unsafe fn from_raw_parts(ptr: *mut T, len: usize) -> Self

Creates a new empty Buffer from a ptr and a len.

Panics

If ptr is null.

pub fn size_in_bytes(len: usize) -> usize

Total number of bytes in the buffer.

pub fn uninitialized(len: usize) -> Result<Self, AllocError>

Create a mirrored buffer containing len Ts where the first half of the buffer is mirrored into the second half.
