Struct ConversationBufferMemory 

pub struct ConversationBufferMemory { /* private fields */ }

Conversation Buffer Memory

Saves all conversation history in memory.

Example

use lc_memory::ConversationBufferMemory;

let mut memory = ConversationBufferMemory::new();

// Save conversation
let inputs = HashMap::from([("input".to_string(), "Hello".to_string())]);
let outputs = HashMap::from([("output".to_string(), "Hi!".to_string())]);
memory.save_context(&inputs, &outputs).await?;

// Load memory
let memory_vars = memory.load_memory_variables(&HashMap::new()).await?;
println!("{:?}", memory_vars.get("history"));
