Struct ShiftBuffer 

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

Implementations

impl<T: Default + Copy> ShiftBuffer<T>

pub fn new(init_size: usize) -> Self

pub fn shrink(&mut self, n: usize) -> Pointer

Moves the lower end of the window by n.

pub fn extend(&mut self, n: usize) -> Pointer

Moves the upper end of the window by n.

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

Make room in the buffer for more data.

If the upper end of the window is not at the stop position of the internal buffer, this method has no effect on the state of the buffer.

Otherwise, it performs either of two operations: if the lower end is at the beginning of the buffer (the window covers the entire buffer), the buffer is extended. Otherwise, the buffer is shifted; i.e., all entries prior to the lower end are discarded and the content is moved to the beginning of the buffer.

In all cases, the return value of this method is the same as for ShiftBuffer::free.

pub fn shift(&mut self)

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

pub fn lower(&self) -> Pointer

pub fn upper(&self) -> Pointer

pub fn relative_pos(&self, p: Pointer) -> usize

pub fn clone_window(&self) -> ShiftBuffer<T>

Create a shift buffer that contains a copy of the current window.
