Struct GraphData 

pub struct GraphData {
    pub nodes: Vec<NodeRec>,
    pub edges: Vec<EdgeRec>,
    pub metadata: Vec<Option<MetadataRec>>,
}

Graph data container for serialization

Format compatible with StorageManager file layout:

• Node count (u64 LE)
• Node records (N * 72 bytes)
• Edge count (u64 LE)
• Edge records (M * 48 bytes)
• Metadata count (u64 LE)
• Metadata records (K * 176 bytes)

Fields

nodes: Vec<NodeRec>

edges: Vec<EdgeRec>

metadata: Vec<Option<MetadataRec>>

Implementations

impl GraphData

pub fn to_bytes(&self) -> Vec<u8>

Serialize graph data to bytes

pub fn from_bytes(bytes: &[u8]) -> Result<Self>

Deserialize graph data from bytes

pub fn required_capacity(&self) -> usize

Calculate required capacity for storing this graph data
