Enum NodeState

pub enum NodeState<T> {
    Free,
    Allocated,
    Valued(T),
}

State of interval tree node.

Valid state transitions:

• None -> Free: IntervalTree::insert()
• None -> Valued: IntervalTree::insert()
• Free -> Allocated: IntervalTree::allocate()
• Allocated -> Valued(T): IntervalTree::update()
• Valued -> Valued(T): IntervalTree::update()
• Allocated -> Free: IntervalTree::free()
• Valued(T) -> Free: IntervalTree::free()
• • -> None: IntervalTree::delete()

Variants

Free

Node is free

Allocated

Node is allocated but without associated data

Valued(T)

Node is allocated with associated data.

Trait Implementations

impl<T: Clone> Clone for NodeState<T>

fn clone(&self) -> NodeState<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for NodeState<T>

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

Formats the value using the given formatter.

impl<T> From<NodeState<T>> for Option<T>

fn from(n: NodeState<T>) -> Option<T>

Converts to this type from the input type.

impl<T: Ord> Ord for NodeState<T>

fn cmp(&self, other: &NodeState<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq for NodeState<T>

fn eq(&self, other: &NodeState<T>) -> 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.

impl<T: PartialOrd> PartialOrd for NodeState<T>

fn partial_cmp(&self, other: &NodeState<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
