Struct SasLinkState 

pub struct SasLinkState {
    pub epsilon: f64,
    pub log_delta: f64,
    pub delta: f64,
}

Runtime SAS link state with cached positive tail parameter.

Fields

epsilon: f64

log_delta: f64

Raw optimization parameter.

delta: f64

Effective tail parameter delta used in evaluation. With current bounded parameterization: delta = exp(B * tanh(log_delta / B)), B = SAS_LOG_DELTA_BOUND.

Implementations

impl SasLinkState

pub fn new(raw_epsilon: f64, raw_log_delta: f64) -> Result<Self, String>

Construct SAS state from raw optimizer parameters using the same bounded transform used everywhere in fitting/evaluation.

Trait Implementations

impl Clone for SasLinkState

fn clone(&self) -> SasLinkState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SasLinkState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SasLinkState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl InverseLinkKernel for SasLinkState

fn jet(&self, eta: f64) -> Result<InverseLinkJet, EstimationError>

fn param_partials( &self, eta: f64, ) -> Result<Option<LinkParamPartials>, EstimationError>

impl PartialEq for SasLinkState

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for SasLinkState
