Struct SqliteStorage 

pub struct SqliteStorage { /* private fields */ }

SQLite backend implementation

Wraps a rusqlite Connection and implements StorageTrait using direct SQL queries to Magellan’s cfg_blocks table.

Implementations

impl SqliteStorage

pub fn open(db_path: &StdPath) -> Result<Self>

Open SQLite database at the given path

Arguments

• db_path - Path to the SQLite database file

Returns

• Ok(SqliteStorage) - Storage instance ready for queries
• Err(...) - Error if file cannot be opened

Examples

let storage = SqliteStorage::open("codegraph.db")?;

pub fn conn(&self) -> &Connection

Get a reference to the underlying Connection

This is useful for legacy code that needs direct SQL access.

Trait Implementations

impl Debug for SqliteStorage

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

Formats the value using the given formatter.

impl StorageTrait for SqliteStorage

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

Get CFG blocks for a function from SQLite backend

Queries Magellan’s cfg_blocks table for all blocks belonging to the given function_id, ordered by block ID.

Arguments

• function_id - ID of the function in graph_entities

Returns

• Ok(Vec<CfgBlockData>) - Vector of CFG block data
• Err(...) - Error if query fails

Note

• Uses prepare_cached for performance on repeated calls
• Returns empty Vec if function has no CFG blocks (not an error)

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

Get entity by ID from SQLite backend

Queries the graph_entities table for the entity with the given ID.

Arguments

• entity_id - ID of the entity

Returns

• Some(GraphEntity) - Entity if found
• None - Entity not found

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

Get cached paths for a function from SQLite backend

Queries the cfg_paths table for cached enumerated paths.

Arguments

• function_id - ID of the function

Returns

• Ok(Some(paths)) - Cached paths if available
• Ok(None) - No cached paths
• Err(...) - Error if query fails
