Struct NodeRecord 

#[repr(C)]
pub struct NodeRecord {
    pub id: NodeId,
    pub epoch: EpochId,
    pub props_offset: u32,
    pub label_count: u16,
    pub _reserved: u16,
    pub props_count: u16,
    pub flags: NodeFlags,
    pub _padding: u32,
}

The compact, cache-line friendly representation of a node.

This struct is exactly 32 bytes and is used for the primary node storage. Properties and labels are stored separately for flexibility. Fields are ordered to minimize padding: u64s first, then u32, then u16s.

Fields

id: NodeId

Unique node identifier.

epoch: EpochId

Epoch this record was created in.

props_offset: u32

Offset into the property arena.

label_count: u16

Number of labels on this node (labels stored externally).

_reserved: u16

Reserved for future use / alignment.

props_count: u16

Number of properties.

flags: NodeFlags

Flags (deleted, has_version, etc.).

_padding: u32

Padding to maintain 32-byte size.

Implementations

impl NodeRecord

pub const FLAG_DELETED: u16

Flag indicating the node is deleted.

pub const FLAG_HAS_VERSION: u16

Flag indicating the node has version history.

pub const fn new(id: NodeId, epoch: EpochId) -> Self

Creates a new node record.

pub const fn is_deleted(&self) -> bool

Checks if this node is deleted.

pub fn set_deleted(&mut self, deleted: bool)

Marks this node as deleted.

pub const fn label_count(&self) -> u16

Returns the number of labels on this node.

pub fn set_label_count(&mut self, count: u16)

Sets the label count.
