Struct CapacitySpec 

pub struct CapacitySpec {
    pub resource_name: String,
    pub current_capacity: f64,
    pub current_usage: f64,
    pub growth_rate: f64,
    pub headroom_factor: f64,
}

A capacity planning resource specification.

Fields

resource_name: String

current_capacity: f64

current_usage: f64

growth_rate: f64

Expected growth rate per period (fraction, e.g. 0.1 = 10%).

headroom_factor: f64

Safety headroom factor (e.g. 1.2 = 20% buffer).

Implementations

impl CapacitySpec

pub fn new( resource_name: &str, current_capacity: f64, current_usage: f64, growth_rate: f64, headroom_factor: f64, ) -> Self

pub fn utilization(&self) -> f64

pub fn predicted_usage(&self, periods: u32) -> f64

Predicted usage after periods time periods with compound growth.

pub fn required_capacity(&self, periods: u32) -> f64

Required capacity to handle predicted usage with headroom.

pub fn periods_until_full(&self) -> Option<u32>

Periods until capacity is breached (without headroom).
