Struct im_pathtree::NodeId

pub struct NodeId(/* private fields */);

Fast, ephemeral node identifier.

Unique across all in-memory nodes within a single process. Identifiers are re-generated and assigned when the process is restarted and must not be stored permanently!

Implementations

impl NodeId

pub fn new() -> Self

Generate a new, unique identifier.

Only the first usize::MAX identifiers are guaranteed to be unique. All following identifiers will be duplicates of previous ones.

The node IDs are unique within a single process, even across multiple trees. Different nodes always have different IDs, no matter if they are in the same tree or not.

let foo_id = NodeId::new();
let bar_id = NodeId::new();
assert_ne!(foo_id, bar_id);

Trait Implementations

impl Clone for NodeId

fn clone(&self) -> NodeId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NodeId

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

Formats the value using the given formatter.

impl Display for NodeId

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

Formats the value using the given formatter.

impl Hash for NodeId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NodeId

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

This method tests for self and other values to be equal, and is used by ==.

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

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