Struct ScaleDownReport 

pub struct ScaleDownReport {
    pub removed: u16,
    pub refused_busy: u16,
    pub clean_failures: u16,
    pub retained: u16,
    pub attempts_unreadable: bool,
}

What one scale-down request did.

Fields

removed: u16

Terminal attempts whose runtime was removed.

refused_busy: u16

Attempts executing a job. Removed nothing, left busy.

clean_failures: u16

Terminal attempts whose runtime could not be removed.

retained: u16

Live attempts that are not yet busy. Also removed nothing: capacity is reclaimed only when an attempt reaches a terminal state.

attempts_unreadable: bool

The host’s attempt set could not be read, so every other field here is meaningless rather than zero.

This is the same distinction ReconcileReport::attempts_unreadable draws, and it is here for the same reason: a default ScaleDownReport and a scale-down that could not see the machine are both all-zeros, and they mean opposite things — “there was nothing to reclaim” against “we do not know what there was”. Check Self::is_conclusive before reading a zero as an answer.

Implementations

impl ScaleDownReport

pub const fn is_conclusive(&self) -> bool

Whether the counts here describe the machine at all.

false means the attempt set could not be read, so every zero is “unknown” rather than “none”.
