Struct CacheCapacity 

pub struct CacheCapacity(/* private fields */);

A non-zero cache capacity

Ensures caches always have at least 1 slot available

Implementations

impl CacheCapacity

pub const DEFAULT: Self

Default pool size

pub const fn new(value: usize) -> Option<Self>

Create a new CacheCapacity, returning None if value is 0

pub const fn get(&self) -> usize

Get the value as usize

Trait Implementations

impl Clone for CacheCapacity

fn clone(&self) -> CacheCapacity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheCapacity

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CacheCapacity

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CacheCapacity

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

Formats the value using the given formatter.

impl From<CacheCapacity> for usize

fn from(cap: CacheCapacity) -> Self

Converts to this type from the input type.

impl Hash for CacheCapacity

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CacheCapacity

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

impl Serialize for CacheCapacity

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
