Installation

Note: This is a development library not yet published to crates.io.

Clone and build from source:

git clone https://github.com/njfio/rust-synaptic.git
cd rust-synaptic
cargo build

For use in other projects, add to your Cargo.toml:

[dependencies]
synaptic = { git = "https://github.com/njfio/rust-synaptic.git", features = ["analytics"] }

Quick Start

use synaptic::memory::{MemoryEntry, MemoryType};
use synaptic::memory::storage::create_storage;
use synaptic::StorageBackend;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create storage backend
    let storage = create_storage(StorageBackend::Memory).await?;

    // Create a memory entry
    let entry = MemoryEntry::new(
        "user_preference".to_string(),
        "Dark mode enabled".to_string(),
        MemoryType::ShortTerm,
    );

    // Store the memory
    storage.store(&entry).await?;

    // Retrieve the memory
    if let Some(retrieved) = storage.retrieve("user_preference").await? {
        println!("Retrieved: {}", retrieved.value);
    }

    // Search for memories
    let results = storage.search("dark mode", 10).await?;
    println!("Found {} related memories", results.len());

    Ok(())
}
