Struct AutoscaleConfig 

pub struct AutoscaleConfig { /* private fields */ }

The autoscale half of PolicyMode.

Every field an Autoscale policy requires lives here, unconditionally. That is the whole trick: there is no Option to be None and no separate validator to forget, so “an autoscale policy with no capacity ceiling” is not a state this program can hold in memory, let alone persist.

Implementations

impl AutoscaleConfig

pub fn new( routing_labels: RoutingLabels, min_capacity: u16, max_capacity: NonZeroU16, ) -> Result<Self, PolicyError>

Errors

PolicyError::InvertedCapacityRange when min > max. Validated here so clamp(demand, min, max) in crate::capacity is always well-defined — an inverted range makes clamp panic in Rust, so this is not a stylistic check.

pub fn v1( routing_labels: RoutingLabels, max_capacity: NonZeroU16, ) -> Result<Self, PolicyError>

The v1 shape: min_capacity fixed at 0 (D7).

Errors

Never fails, because 0 cannot exceed a NonZeroU16; the Result is kept so that lifting the D7 restriction later is not a signature change.

pub fn routing_labels(&self) -> &RoutingLabels

pub fn routing_labels_mut(&mut self) -> &mut RoutingLabels

pub const fn min_capacity(&self) -> u16

pub const fn max_capacity(&self) -> NonZeroU16

pub fn set_max_capacity( &mut self, max_capacity: NonZeroU16, ) -> Result<(), PolicyError>

Errors

PolicyError::InvertedCapacityRange if the new ceiling is below the existing floor.
