Enum TargetPopulation 

#[non_exhaustive]
pub enum TargetPopulation {
    AllObserved,
    Treated,
    Untreated,
    Environment(EnvironmentId),
    Predicate(PredicateExpr),
    CustomDistribution(DistributionRef),
}

Target population for an effect query.

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.

AllObserved

All observed units.

Treated

Treated units only.

Untreated

Untreated units only.

Environment(EnvironmentId)

Environment-restricted population.

Predicate(PredicateExpr)

Predicate-selected units (PredicateExpr).

CustomDistribution(DistributionRef)

Custom target distribution handle (weights via super::PopulationRegistry).

Implementations

impl TargetPopulation

pub fn resolve( &self, n: usize, treatment: Option<&[f64]>, registry: Option<&PopulationRegistry>, ) -> Result<PopulationSelection, QueryError>

Resolve this population over n rows.

treatment is required for Self::Treated / Self::Untreated (binary 0/1 column, length n). Named predicates and custom distributions require registry.

Errors

Missing registry bindings, shape mismatches, or unknown variants.

impl TargetPopulation

pub fn validate(&self) -> Result<(), QueryError>

Validate population geometry for Planned / structured variants.

Errors

Empty predicate name or empty row set.

Trait Implementations

impl Clone for TargetPopulation

fn clone(&self) -> TargetPopulation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TargetPopulation

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

Formats the value using the given formatter.

impl Eq for TargetPopulation

impl Hash for TargetPopulation

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 TargetPopulation

fn eq(&self, other: &TargetPopulation) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
