Struct EdgeRef 

pub struct EdgeRef<'a> { /* private fields */ }

A zero-copy reference to an edge stored in memory-mapped data.

This struct provides lazy field access directly from the underlying byte slice, avoiding the overhead of deserializing into an owned struct.

Lifetime

The lifetime 'a is tied to the underlying memory-mapped region. The EdgeRef is only valid as long as the mmap is valid.

Implementations

impl<'a> EdgeRef<'a>

pub fn new(bytes: &'a [u8; 128]) -> Self

Create a new EdgeRef from a byte slice.

Safety

The caller must ensure the slice is exactly 128 bytes and contains a valid edge representation.

pub fn try_from_slice(bytes: &'a [u8]) -> Option<Self>

Try to create an EdgeRef from a slice (with length check).

pub fn edge_id(&self) -> u128

Get the edge ID (u128 at offset 0).

pub fn timestamp_us(&self) -> u64

Get the timestamp in microseconds (u64 at offset 16).

pub fn tenant_id(&self) -> u64

Get the tenant ID (u64 at offset 24).

pub fn project_id(&self) -> u16

Get the project ID (u16 at offset 32).

pub fn source_node_id(&self) -> u128

Get the source node ID (u128 at offset 34).

pub fn target_node_id(&self) -> u128

Get the target node ID (u128 at offset 50).

pub fn edge_type(&self) -> u8

Get the edge type (u8 at offset 66).

pub fn flags(&self) -> u8

Get the flags byte (u8 at offset 67).

pub fn is_deleted(&self) -> bool

Check if this edge is a tombstone (deleted).

pub fn payload_ref(&self) -> &[u8]

Get the payload reference (hash or inline data at offset 68).

pub fn checksum(&self) -> u32

Get the checksum (u32 at offset 124).

pub fn as_bytes(&self) -> &[u8; 128]

Get the raw bytes.

pub fn verify_checksum(&self) -> bool

Verify the edge checksum.

Trait Implementations

impl<'a> Clone for EdgeRef<'a>

fn clone(&self) -> EdgeRef<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EdgeRef<'_>

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

Formats the value using the given formatter.

impl Ord for EdgeRef<'_>

fn cmp(&self, other: &Self) -> 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 EdgeRef<'_>

fn eq(&self, other: &Self) -> 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 EdgeRef<'_>

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