Struct TimeWindow 

pub struct TimeWindow {
    pub span: Duration,
    pub samples: usize,
}

The span of time one piece of evidence covers (§11.3).

A measurement read from the current sample and a count taken over fifteen samples are both evidence, but they support very different claims, so the window travels with the measurement rather than being described in prose.

Fields

span: Duration

Monotonic span between the oldest and newest sample the evidence covers.

samples: usize

How many samples were actually read.

Samples whose input was unavailable are not counted: §26 forbids treating a missing reading as a reading (§8.2).

Implementations

impl TimeWindow

pub const CURRENT_SAMPLE: Self

A single reading from the snapshot being evaluated.

pub const fn new(span: Duration, samples: usize) -> Self

A window covering samples readings across span.

pub const fn moving_average(span: Duration) -> Self

A single reading that is itself a moving average, such as a Linux PSI avg10 figure.

One read of avg10 already summarizes ten seconds of kernel-measured stall time, so the honest window is those ten seconds even though only one sample was read.

pub const fn is_current_sample(&self) -> bool

Whether this is a single instantaneous reading.

pub fn render(&self) -> String

Renders the window for the Inspect screen (§7.5).
