Struct SyntaxTree

pub struct SyntaxTree<T>(/* private fields */);

A doubly linked syntax tree.

Implementations

impl<T> SyntaxTree<T>

pub fn cursor(&self) -> Cursor<'_, T>

Provides a cursor at the front element.

pub fn cursor_mut(&mut self) -> CursorMut<'_, T>

Provides a cursor with editing operation at the root element.

pub fn len(&self) -> usize

Returns the length of the OptionalNode.

This operation should compute in O(n) time.

pub fn is_empty(&self) -> bool

Returns true if the tree contains no elements.

pub fn iter(&self) -> Iter<'_, T>

Returns a depth-first iterator with references.

pub fn iter_mut(&mut self) -> IterMut<'_, T>

Returns a depth-first iterator with mutable references.

Trait Implementations

impl<T: Clone> Clone for SyntaxTree<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for SyntaxTree<T>

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

Formats the value using the given formatter.

impl<T> Default for SyntaxTree<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: Display> Display for SyntaxTree<T>

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

Formats the value using the given formatter.

impl<T> Drop for SyntaxTree<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T> From<T> for SyntaxTree<T>

fn from(element: T) -> Self

Converts to this type from the input type.

impl<T> PartialEq for SyntaxTree<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.
