Struct NodeOptions 

pub struct NodeOptions { /* private fields */ }

Optional metadata applied when inserting one retained node.

This keeps identity and placement concerns in one place so the builder API does not need separate keyed_* and *_with_policy method families.

Implementations

impl NodeOptions

pub const fn new() -> Self

Creates default options with automatic placement and no explicit key.

pub const fn with_policy(policy: Policy) -> Self

Creates options with an explicit placement policy.

pub fn keyed<K: Hash>(key: K) -> Self

Creates options keyed from the provided value.

pub const fn policy(self, policy: Policy) -> Self

Replaces the placement policy.

pub fn key<K: Hash>(self, key: K) -> Self

Stores a stable hashed key for this node.

Trait Implementations

impl Clone for NodeOptions

fn clone(&self) -> NodeOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeOptions

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

Formats the value using the given formatter.

impl Default for NodeOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for NodeOptions

fn eq(&self, other: &NodeOptions) -> 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.
