Struct RateLimiterSet 

pub struct RateLimiterSet { /* private fields */ }

Per-class rate limiter set (BEP 40 / libtorrent parity).

Maintains separate upload/download buckets for TCP and uTP, plus global upload/download buckets. Uses check-before-consume pattern to avoid partial consumption when one bucket has capacity but another doesn’t.

Implementations

impl RateLimiterSet

pub fn new( tcp_upload_rate: u64, tcp_download_rate: u64, utp_upload_rate: u64, utp_download_rate: u64, global_upload_rate: u64, global_download_rate: u64, ) -> Self

Create a new rate limiter set. Rate of 0 = unlimited.

pub fn refill(&mut self, elapsed: Duration)

Refill all buckets proportional to elapsed time.

pub fn try_consume_upload( &mut self, amount: u64, transport: PeerTransport, ) -> bool

Try to consume upload tokens for the given transport class.

Checks both the class bucket and global bucket before consuming either, to avoid partial consumption without refund.

pub fn try_consume_download( &mut self, amount: u64, transport: PeerTransport, ) -> bool

Try to consume download tokens for the given transport class.

pub fn set_rates( &mut self, tcp_upload: u64, tcp_download: u64, utp_upload: u64, utp_download: u64, global_upload: u64, global_download: u64, )

Update per-class rates at runtime (e.g., from apply_settings).

pub fn apply_mixed_mode( &mut self, algorithm: MixedModeAlgorithm, tcp_peers: usize, utp_peers: usize, global_upload_rate: u64, )

Apply mixed-mode bandwidth allocation based on peer transport composition. Only adjusts upload — download is not throttled by transport type.
