v-authorization-lmpl

LMDB implementation for Veda authorization system.

Description

This crate provides LMDB-based storage backend for the Veda authorization framework. It implements the AuthorizationContext trait from v_authorization crate using Lightning Memory-Mapped Database (LMDB).

Features

• High-performance authorization data storage using LMDB
• Optional caching layer for improved performance
• Statistics collection support
• Thread-safe read operations

Usage

use v_authorization_lmpl::LmdbAzContext;

// Create with default settings
let mut az_ctx = LmdbAzContext::default();

// Create with custom max read counter
let mut az_ctx = LmdbAzContext::new(10000);

// Create with full configuration
let mut az_ctx = LmdbAzContext::new_with_config(
    10000,
    Some("tcp://localhost:9999".to_string()),
    Some("full".to_string()),
    Some(true)
);

Configuration

The context can be configured with:

• max_read_counter: Number of authorization operations before database reconnection
• stat_collector_url: Optional URL for statistics collection
• stat_mode: Statistics collection mode ("full", "minimal", or "none")
• use_cache: Enable/disable authorization cache

Dependencies

• lmdb-rs-m: LMDB Rust bindings
• v_authorization: Core authorization framework
• nng: Nanomsg-next-generation for statistics reporting
