Struct NodeId 

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

A 32-byte node identity (FDD-03 §9.3). Minted once at node creation and preserved across rename; encoded as a bytes field, not an object_id.

Implementations

impl NodeId

pub const fn from_bytes(bytes: [u8; 32]) -> Self

Wrap raw bytes as a node identity. Unchecked: accepts any 32 bytes, including the reserved all-zero value. Intended for fixtures and round-trip construction; production decode paths MUST use NodeId::try_from_bytes.

pub fn try_from_bytes(bytes: [u8; 32]) -> Result<Self>

Wrap validated bytes as a node identity, rejecting the all-zero reserved value. Production operation decoders use this.

pub const fn as_bytes(&self) -> &[u8; 32]

Borrow the raw identity bytes.

pub fn is_zero(&self) -> bool

True if this is the reserved all-zero identity, which is never valid in a persisted node-bearing operation.

Trait Implementations

impl Clone for NodeId

fn clone(&self) -> NodeId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NodeId

impl Debug for NodeId

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

Formats the value using the given formatter.

impl Eq for NodeId

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 Ord for NodeId

fn cmp(&self, other: &NodeId) -> 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 PartialEq for NodeId

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

fn partial_cmp(&self, other: &NodeId) -> 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.
