Trait TlsProvider 

pub trait TlsProvider: Send + Sync {
    // Required methods
    fn get_worker_id(&self) -> Option<usize>;
    fn with_hit_buf(&self, f: &mut dyn FnMut(&mut ([usize; 64], usize)));
    fn with_l1_filter(&self, f: &mut dyn FnMut(&mut ([u8; 4096], usize)));
    fn with_last_flush_tick(&self, f: &mut dyn FnMut(&mut u64));
}

Trait for plug-and-play Thread-Local Storage (TLS) in no_std or custom RTOS environments.

Enables thread-local batching of hits and L1 probation filtering on platforms where standard thread_local! is not available.

Required Methods

fn get_worker_id(&self) -> Option<usize>

Get the current worker thread ID (0..config.threads).

Returns None if the thread is not registered or cannot be resolved.

fn with_hit_buf(&self, f: &mut dyn FnMut(&mut ([usize; 64], usize)))

Access the thread-local Hit Buffer array.

The provider must execute the given closure with a mutable reference to the current thread’s batch buffer: ([usize; 64], usize).

fn with_l1_filter(&self, f: &mut dyn FnMut(&mut ([u8; 4096], usize)))

Access the thread-local L1 Probation Filter.

The provider must execute the given closure with a mutable reference to the current thread’s L1 probation filter state: ([u8; 4096], usize).

fn with_last_flush_tick(&self, f: &mut dyn FnMut(&mut u64))

Access the thread-local Last Flush Tick.

The provider must execute the given closure with a mutable reference to the current thread’s last flush tick value.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
