Struct IndexedPlanCacheLimits 

pub struct IndexedPlanCacheLimits { /* private fields */ }

Limits for the CPU indexed-plan cache.

A zero entry or byte limit disables retention. Limits apply independently to each initialized CPU execution engine.

Examples

use tenferro_cpu::IndexedPlanCacheLimits;

let limits = IndexedPlanCacheLimits::new(32, 1024 * 1024);
assert_eq!(limits.max_entries(), 32);
assert_eq!(limits.max_retained_bytes(), 1024 * 1024);

Implementations

impl IndexedPlanCacheLimits

pub const fn new(max_entries: usize, max_retained_bytes: usize) -> Self

Construct indexed-plan cache limits.

Examples

use tenferro_cpu::IndexedPlanCacheLimits;

let limits = IndexedPlanCacheLimits::new(8, 4096);
assert_eq!(limits.max_entries(), 8);

pub const fn max_entries(self) -> usize

Maximum retained plan count per CPU execution engine.

Examples

use tenferro_cpu::IndexedPlanCacheLimits;

assert_eq!(IndexedPlanCacheLimits::new(8, 4096).max_entries(), 8);

pub const fn max_retained_bytes(self) -> usize

Maximum logical retained bytes per CPU execution engine.

Examples

use tenferro_cpu::IndexedPlanCacheLimits;

assert_eq!(
    IndexedPlanCacheLimits::new(8, 4096).max_retained_bytes(),
    4096
);

Trait Implementations

impl Clone for IndexedPlanCacheLimits

fn clone(&self) -> IndexedPlanCacheLimits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexedPlanCacheLimits

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

Formats the value using the given formatter.

impl PartialEq for IndexedPlanCacheLimits

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