Struct NullRecorder

pub struct NullRecorder<E, R>
where
    E: Env,
    R: ReplayBufferBase,
{ /* private fields */ }

A recorder that discards all records without storing them.

The NullRecorder implements the Recorder trait but ignores all records passed to it. This is useful in several scenarios:

• During debugging when you want to disable logging temporarily
• In testing environments where record storage is not needed
• When you want to measure performance without the overhead of record storage
• As a placeholder when record storage is optional

Type Parameters

• E - The environment type that implements the Env trait
• R - The replay buffer type that implements the ReplayBufferBase trait

Implementations

impl<E, R> NullRecorder<E, R>

where E: Env, R: ReplayBufferBase,

pub fn new() -> Self

Creates a new null recorder.

Returns

A new instance of NullRecorder that will discard all records.

Trait Implementations

impl<E, R> Recorder<E, R> for NullRecorder<E, R>

where E: Env, R: ReplayBufferBase,

fn write(&mut self, _record: Record)

Discards the given record without storing it.

This method is a no-op and immediately discards the record.

Arguments

• _record - The record to be discarded

fn store(&mut self, _record: Record)

Discards the given record without storing it.

This method is a no-op and immediately discards the record.

Arguments

• _record - The record to be discarded

fn flush(&mut self, _step: i64)

No-op flush operation.

This method does nothing as no records are stored.

Arguments

• _step - The step at which to flush (ignored)

fn save_model(&self, base: &Path, agent: &Box<dyn Agent<E, R>>) -> Result<()>

Saves the current state of the agent’s model.

fn load_model( &self, base: &Path, agent: &mut Box<dyn Agent<E, R>>, ) -> Result<()>

Loads a previously saved model state into the agent.
