Struct EngineBuilder 

pub struct EngineBuilder { /* private fields */ }

Configures and builds a loaded Engine from OXGTOPO bytes.

Implementations

impl EngineBuilder

pub fn new() -> Self

Creates an empty builder (no snapshot bytes yet).

pub fn snapshot_owned(self, bytes: Vec<u8>) -> Self

Supplies owned snapshot bytes to load.

pub fn overlay(self, overlay: OverlayState) -> Self

Sets overlay state applied after open.

pub fn config(self, config: Config) -> Self

Sets operational configuration validated at build time.

pub fn build(self) -> Result<Engine, PostgresGraphError>

Validates the artifact and opens forward CSR plus inbound CSC views once.

Errors

Returns PostgresGraphError when bytes are missing, invalid, or layouts disagree.

Performance

This function is O(s + n + m); queries are O(1) to borrow topology afterward.
