Struct RecordId 

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

Unique identifier for a record within a tree.

RecordId is a lightweight handle that refers to a record by its index in the tree’s internal storage. It is only valid within the context of the tree it was created from.

Implementations

impl RecordId

pub const ROOT: RecordId

The root record ID (index 0).

pub const fn new(index: u32) -> Self

Create a new RecordId from an index.

pub const fn index(self) -> u32

Get the underlying index.

pub fn from_usize(index: usize) -> Self

Create a RecordId from a usize index.

pub fn as_usize(self) -> usize

Get the index as usize.

Trait Implementations

impl Clone for RecordId

fn clone(&self) -> RecordId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecordId

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

Formats the value using the given formatter.

impl Default for RecordId

fn default() -> RecordId

Returns the “default value” for a type.

impl Display for RecordId

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

Formats the value using the given formatter.

impl From<RecordId> for u32

fn from(id: RecordId) -> Self

Converts to this type from the input type.

impl From<RecordId> for usize

fn from(id: RecordId) -> Self

Converts to this type from the input type.

impl From<u32> for RecordId

fn from(index: u32) -> Self

Converts to this type from the input type.

impl From<usize> for RecordId

fn from(index: usize) -> Self

Converts to this type from the input type.

impl Hash for RecordId

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 RecordId

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