Enum ParameterKind 

#[non_exhaustive]
pub enum ParameterKind {
    Temperature,
    TopP,
    TopK,
    FrequencyPenalty,
    PresencePenalty,
    RetrievalTopK,
    SimilarityThreshold,
    TemporalDecay,
}

Identifies a tunable parameter in the experiment search space.

Each variant corresponds to a field in ConfigSnapshot and maps to a named key in SearchSpace via ParameterKind::as_str.

The enum is #[non_exhaustive] — new parameters may be added in future versions without a breaking change.

Examples

use zeph_experiments::ParameterKind;

assert_eq!(ParameterKind::Temperature.as_str(), "temperature");
assert!(ParameterKind::TopK.is_integer());
assert!(!ParameterKind::TopP.is_integer());

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Temperature

LLM sampling temperature (float, typically [0.0, 2.0]).

TopP

Top-p (nucleus) sampling probability (float, [0.0, 1.0]).

TopK

Top-k sampling cutoff (integer).

FrequencyPenalty

Frequency penalty applied to already-seen tokens (float, [-2.0, 2.0]).

PresencePenalty

Presence penalty applied to already-seen topics (float, [-2.0, 2.0]).

RetrievalTopK

Number of memory chunks to retrieve per query (integer).

SimilarityThreshold

Minimum cosine similarity score for cross-session memory recall (float).

TemporalDecay

Half-life in days for temporal memory decay (float).

Implementations

impl ParameterKind

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

Return the canonical snake_case name of this parameter.

The returned string matches the key used in config files and experiment storage. It is identical to the #[serde(rename_all = "snake_case")] serialization form.

Examples

use zeph_experiments::ParameterKind;

assert_eq!(ParameterKind::FrequencyPenalty.as_str(), "frequency_penalty");

pub fn is_integer(&self) -> bool

Returns true if this parameter has integer semantics.

Integer parameters produce a VariationValue::Int in ConfigSnapshot::diff and are rounded before being applied to generation overrides.

Examples

use zeph_experiments::ParameterKind;

assert!(ParameterKind::TopK.is_integer());
assert!(ParameterKind::RetrievalTopK.is_integer());
assert!(!ParameterKind::Temperature.is_integer());

Trait Implementations

impl Clone for ParameterKind

fn clone(&self) -> ParameterKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParameterKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ParameterKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ParameterKind

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

Formats the value using the given formatter.

impl Hash for ParameterKind

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 ParameterKind

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
