Enum HashStrategyKind 

pub enum HashStrategyKind {
    Double,
    EnhancedDouble,
    Triple,
}

Enum over the built-in HashStrategy implementors for serialization and runtime selection.

Use this in struct fields and method signatures where a trait object or type parameter would be inconvenient.

Examples

use bloomcraft::hash::strategies::HashStrategyKind;

let kind = HashStrategyKind::EnhancedDouble;
assert_eq!(kind.name(), "EnhancedDoubleHashing");
assert_eq!(HashStrategyKind::default(), HashStrategyKind::EnhancedDouble);

Variants

Double

gᵢ = (h₁ + i·h₂) mod m

EnhancedDouble

gᵢ = (h₁ + i·h₂ + (i² + i)/2) mod m

Triple

gᵢ = (h₁ + i·h₂ + i²·h₃) mod m

Implementations

impl HashStrategyKind

pub fn name(&self) -> &'static str

Stable name matching the corresponding HashStrategy implementor’s HashStrategy::name output. Used in metadata and serialization.

Trait Implementations

impl Clone for HashStrategyKind

fn clone(&self) -> HashStrategyKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HashStrategyKind

impl Debug for HashStrategyKind

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

Formats the value using the given formatter.

impl Default for HashStrategyKind

fn default() -> HashStrategyKind

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HashStrategyKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for HashStrategyKind

impl PartialEq for HashStrategyKind

fn eq(&self, other: &HashStrategyKind) -> 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 HashStrategyKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
