Struct AdTransformCacheLimits 

pub struct AdTransformCacheLimits { /* private fields */ }

Retention limits for AD transform graph caches.

The retained-byte limit is a logical payload estimate, not process RSS.

Examples

use std::num::NonZeroUsize;
use tenferro_ad::AdTransformCacheLimits;

let limits = AdTransformCacheLimits::new(NonZeroUsize::new(4).unwrap());
assert_eq!(limits.max_entries().get(), 4);
assert!(limits.max_retained_bytes().is_some());

Implementations

impl AdTransformCacheLimits

pub fn new(max_entries: NonZeroUsize) -> Self

Create AD transform cache limits with the default retained-byte bound.

Examples

use std::num::NonZeroUsize;
use tenferro_ad::AdTransformCacheLimits;

let limits = AdTransformCacheLimits::new(NonZeroUsize::new(2).unwrap());
assert_eq!(limits.max_entries().get(), 2);

pub fn max_entries(self) -> NonZeroUsize

Return the maximum number of retained AD transform entries.

Examples

use tenferro_ad::AdTransformCacheLimits;

assert!(AdTransformCacheLimits::default().max_entries().get() > 0);

pub fn max_retained_bytes(self) -> Option<NonZeroUsize>

Return the logical retained-byte bound, when one is configured.

Examples

use tenferro_ad::AdTransformCacheLimits;

assert!(AdTransformCacheLimits::default().max_retained_bytes().is_some());

pub fn with_max_retained_bytes(self, max_retained_bytes: NonZeroUsize) -> Self

Return limits with a new logical retained-byte bound.

Examples

use std::num::NonZeroUsize;
use tenferro_ad::AdTransformCacheLimits;

let limits = AdTransformCacheLimits::default()
    .with_max_retained_bytes(NonZeroUsize::new(1024).unwrap());
assert_eq!(limits.max_retained_bytes().unwrap().get(), 1024);

Trait Implementations

impl Clone for AdTransformCacheLimits

fn clone(&self) -> AdTransformCacheLimits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AdTransformCacheLimits

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

Formats the value using the given formatter.

impl Default for AdTransformCacheLimits

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for AdTransformCacheLimits

fn eq(&self, other: &AdTransformCacheLimits) -> 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.
