Struct StalenessPolicy 

pub struct StalenessPolicy {
    pub max_staleness_s: f64,
}

Configurable staleness cap for product selection.

A selection that would rely on a product older than max_staleness_s fails with SelectionError::BeyondStalenessCap rather than returning data past the cap. The Default is DEFAULT_MAX_STALENESS_DAYS.

use sidereon_core::staleness::StalenessPolicy;
use sidereon_core::constants::SECONDS_PER_DAY;
let policy = StalenessPolicy::default();
assert_eq!(policy.max_staleness_s, 3.0 * SECONDS_PER_DAY);
assert_eq!(StalenessPolicy::days(1.0).max_staleness_s, SECONDS_PER_DAY);

Fields

max_staleness_s: f64

Maximum tolerated staleness, seconds.

Implementations

impl StalenessPolicy

pub fn days(days: f64) -> Self

A policy with a cap expressed in days.

pub fn seconds(seconds: f64) -> Self

A policy with a cap expressed in seconds.

Trait Implementations

impl Clone for StalenessPolicy

fn clone(&self) -> StalenessPolicy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for StalenessPolicy

impl Debug for StalenessPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for StalenessPolicy

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for StalenessPolicy

fn eq(&self, other: &StalenessPolicy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
