pub struct Budget {
    pub resource: ResourceType,
    pub limit: u64,
    pub used: u64,
}

A single resource budget: limit, utilisation tracking.

Fields

resource: ResourceType

Which resource this budget governs.

limit: u64

Maximum allowed units.

used: u64

Units consumed so far.

Implementations

impl Budget

pub fn new(resource: ResourceType, limit: u64) -> Self

pub fn remaining(&self) -> u64

How many units remain before the limit is hit.

pub fn utilization(&self) -> f64

Fraction of the budget that has been consumed (used / limit).

Returns 0.0 when limit == 0 to avoid division by zero.
