Struct ExtensionCacheLimits 

pub struct ExtensionCacheLimits { /* private fields */ }

Bounded retention limits for extension runtime caches.

Implementations

impl ExtensionCacheLimits

pub const fn new(max_entries: NonZero<usize>) -> ExtensionCacheLimits

Build limits from a maximum entry count and the default byte bound.

Examples

use std::num::NonZeroUsize;
use tenferro_runtime::ExtensionCacheLimits;

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

pub const fn max_entries(self) -> NonZero<usize>

Maximum entries retained by the store.

pub const fn max_retained_bytes(self) -> Option<NonZero<usize>>

Maximum logical retained bytes, when configured.

pub const fn with_max_retained_bytes( self, max_retained_bytes: NonZero<usize>, ) -> ExtensionCacheLimits

Return limits with a new logical retained-byte bound.

Examples

use std::num::NonZeroUsize;
use tenferro_runtime::ExtensionCacheLimits;

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

Trait Implementations

impl Clone for ExtensionCacheLimits

fn clone(&self) -> ExtensionCacheLimits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtensionCacheLimits

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

Formats the value using the given formatter.

impl Default for ExtensionCacheLimits

fn default() -> ExtensionCacheLimits

Returns the “default value” for a type.

impl PartialEq for ExtensionCacheLimits

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