Struct TransferBudget 

pub struct TransferBudget { /* private fields */ }

Rolling byte accounting against a set of TransferLimits.

Implementations

impl TransferBudget

pub const fn new(limits: TransferLimits) -> Self

pub fn limits(&self) -> TransferLimits

pub fn set_limits(&self, limits: TransferLimits)

Replace the active quotas without discarding recorded usage.

pub fn available(&self, direction: Direction) -> u64

Bytes that may still be transferred for direction right now.

pub fn available_at(&self, direction: Direction, now: Instant) -> u64

Bytes that may still be transferred for direction at now.

The result is the smallest remaining allowance across the configured rolling windows, or u64::MAX when the direction is unlimited.

pub fn can_transfer(&self, direction: Direction, bytes: u64) -> bool

Whether bytes can be transferred for direction without breaking a quota.

pub fn record(&self, direction: Direction, bytes: u64)

Record transferred bytes.

pub fn record_at(&self, direction: Direction, bytes: u64, now: Instant)

Record transferred bytes observed at now.

pub fn used_at( &self, direction: Direction, window: Duration, now: Instant, ) -> u64

Bytes transferred for direction within window ending at now.

pub fn recorded_total(&self) -> u64

Total bytes recorded in all windows (diagnostics).
