ParameterSampler

eqiora::api

Struct ParameterSampler 

pub struct ParameterSampler { /* private fields */ }
Description

Bounded sampler in one admitted Program’s exact ordered Parameter coordinates.

Bounds use coherent SI values in that existing typed input order. This is a deterministic finite-grid sampler, not evidence of statistical independence or a time-indexed stochastic process. No draw happens inside evaluation.

Implementations§

§

impl ParameterSampler

Signature links:§ParameterSampler

pub const GENERATOR: &'static str = "eqiora.parameter-uniform.sha256.v1"

Signature links:GENERATORstr

Exact supported SHA-256 stream derivation and binary64 conversion contract.

pub fn new( program: Arc<DifferentiableProgram>, master: [u8; 32], fixed: &DifferentiableValues, bounds: &[[f64; 2]], ) -> Result<ParameterSampler, Diagnostic>

Signature links:newArcDifferentiableProgramu832DifferentiableValuesf642ResultParameterSamplerDiagnostic

Freeze selected typed inputs and admit 1..=256 finite sampling intervals.

Bounds cover only the remaining Program coordinates, in their original order. A draw retains its absolute Program coordinate index, so fixing another input does not shift its stream. An empty fixed product samples every input. Changing fixed values makes a new explicit sampling request; execution and differentiation never resample.

§Errors

Rejects shape/type-input disagreement and invalid intervals before sampling.

pub const fn master_stream(&self) -> &[u8; 32]

Signature links:master_streamu832

Full master stream identity; no ambient seed is consulted.

pub fn fixed_values(&self) -> &DifferentiableValues

Signature links:fixed_valuesDifferentiableValues

Frozen typed values excluded from random draws, in their selected leaf order.

pub fn bounds(&self) -> &[[f64; 2]]

Signature links:boundsf642

Ordered coherent-SI half-open intervals for the remaining input coordinates.

pub fn sample( &self, identity: &SamplingIdentity, ) -> Result<SampledParameterPoint, Diagnostic>

Signature links:sampleSamplingIdentityResultSampledParameterPointDiagnostic

Freeze one complete typed point. Repeated identities deliberately replay.

Call in any order, partition, worker or retry schedule. The generated values are passed explicitly to DifferentiableProgram::evaluate or EvaluationMapPlan::new; those owners retain numerical admission.

§Errors

Returns the existing typed input admission diagnostic if conversion fails.
