Struct ReplayBuffer 

pub struct ReplayBuffer<T> { /* private fields */ }

Experience replay buffer using reservoir sampling.

This ensures uniform coverage of past experiences for stable learning, preventing catastrophic forgetting as described in the ruvector-gnn crate.

Implementations

pub fn add(&mut self, experience: T)

Add an experience to the buffer using reservoir sampling.

pub fn sample(&self, n: usize) -> Vec<T>

Sample n experiences uniformly at random.

pub fn len(&self) -> usize
