Struct EdgeRef 

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

Type-safe, bounds-checked edge reference

Instead of raw transmute, uses validated constructor with bounds check.

Implementations

impl<'a> EdgeRef<'a>

pub fn new_checked( data: &'a [u8], offset: usize, ) -> Result<Self, ValidationError>

Create a new EdgeRef with bounds and validity checking

Returns Err if:

• offset + EDGE_SIZE > data.len()
• Edge magic is invalid
• Edge CRC does not match

pub unsafe fn new_unchecked(data: &'a [u8], offset: usize) -> Self

Create EdgeRef without validation (unsafe fast path)

Safety

Caller must ensure:

• offset + EDGE_SIZE <= data.len()
• Edge data is valid

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

Get raw bytes

pub fn source_id(&self) -> u64

Get source vertex ID (with bounds check)

pub fn target_id(&self) -> u64

Get target vertex ID (with bounds check)

pub fn weight(&self) -> f64

Get edge weight (with bounds check)

pub fn edge_type(&self) -> u32

Get edge type (with bounds check)

pub fn timestamp(&self) -> u64

Get timestamp (with bounds check)

pub fn payload_bytes(&self) -> Result<&'a [u8], ValidationError>

Get payload bytes with bounds validation

Payload is stored at variable offset within the edge

pub fn verify_crc(&self) -> bool

Verify edge CRC
