Enum Backend 

pub enum Backend {
    Sqlite(SqliteStorage),
}

Storage backend enum (Phase 069-01)

This enum wraps SqliteStorage, KvStorage, or GeometricStorage and delegates StorageTrait methods to the appropriate implementation.

Follows llmgrep’s Backend pattern for consistency across tools.

Variants

Sqlite(SqliteStorage)

SQLite storage backend (traditional, always available)

Implementations

impl Backend

pub fn detect_and_open(db_path: &Path) -> Result<Self>

Detect backend format from database file and open appropriate backend

Uses file extension and magellan’s detection for consistent backend detection.

Arguments

• db_path - Path to the database file

Returns

• Ok(Backend) - Appropriate backend variant
• Err(...) - Error if detection or opening fails

Examples

let backend = Backend::detect_and_open("/path/to/codegraph.db")?;

pub fn is_geometric(&self) -> bool

Check if this is a Geometric backend

pub fn is_sqlite(&self) -> bool

Check if this is a SQLite backend

pub fn is_native_v3(&self) -> bool

Check if this is a Native-V3 backend

pub fn get_cfg_blocks(&self, function_id: i64) -> Result<Vec<CfgBlockData>>

Delegate get_cfg_blocks to inner backend

pub fn get_entity(&self, entity_id: i64) -> Option<GraphEntity>

Delegate get_entity to inner backend

pub fn get_cached_paths(&self, function_id: i64) -> Result<Option<Vec<Path>>>

Delegate get_cached_paths to inner backend
