Struct Cursor

pub struct Cursor<'life, T> { /* private fields */ }

A Cursor is like an iterator, except that it can freely seek back-and-forth. This struct is constructed by the CircularList::cursor function.

Implementations

impl<'life, T> Cursor<'life, T>

pub fn list(&self) -> &CircularList<T>

Returns a reference of the underlying list.

pub fn reset(&mut self)

Returns to its initial position (the head of the list).

pub fn move_next(&mut self)

Moves the cursor to the next element of the CircularList.

pub fn move_prev(&mut self)

Moves the cursor to the previous element of the CircularList.

pub fn value(&self) -> &T

Returns the value of the list element behind the cursor.

Trait Implementations

impl<'life, T: Clone> Clone for Cursor<'life, T>

fn clone(&self) -> Cursor<'life, T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'life, T: Debug> Debug for Cursor<'life, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'life, T: Display> Display for Cursor<'life, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'life, T> PartialEq for Cursor<'life, T>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
