Struct RedbBackend 

pub struct RedbBackend { /* private fields */ }

Redb backend implementation for persistent key-value storage.

This backend uses redb’s ACID transactions to ensure data consistency. All operations are atomic and durable by default.

Thread Safety

The Arc<Database> wrapper allows safe sharing across threads. Redb handles its own internal locking and MVCC.

Implementations

impl RedbBackend

pub fn open<P: AsRef<Path>>(path: P) -> Result<Self, IndexError>

Open or create a Redb database at the given path.

Arguments

• path - The file path where the database will be stored

Returns

• Ok(RedbBackend) - Successfully opened or created database
• Err(IndexError) - Failed to open/create database

Example

use index::RedbBackend;

let backend = RedbBackend::open("/tmp/test.redb").unwrap();
