pub struct FlowQuota { /* private fields */ }

Implementations

impl FlowQuota

pub fn from_config(cfg: QuotaConfig) -> Self

pub fn new( cpu_budget: i64, mem_limit: usize, spawn_burst: i64, spawn_per_sec: i64, send_burst: i64, send_per_sec: i64, ) -> Self

pub fn remaining_cpu(&self) -> i64

pub fn charge_cpu(&self, cost: i64) -> Result<(), QuotaError>

Call once per executed instruction (or every N, in a batch — the batch only thickens trap latency, it does not change the limit).

pub fn alloc(&self, bytes: usize) -> Result<(), QuotaError>

pub fn free(&self, bytes: usize)

pub fn check_spawn(&self) -> Result<(), QuotaError>

pub fn check_send(&self) -> Result<(), QuotaError>

pub fn top_up_cpu(&self, extra: i64)

Reachable only after check_admin against CapTarget::Scheduler.

pub fn mem_used(&self) -> usize
