Enum CausalEvidenceGrade 

pub enum CausalEvidenceGrade {
    Rct,
    QuasiExperimental,
    Observational,
    Theoretical,
}

v0.38: study-design grade backing a causal claim. The grade is what makes the difference between “the data is consistent with X causing Y” (Observational) and “X causes Y” (Rct). The kernel carries the design label so reviewers can re-grade without re-extracting.

Variants

Rct

Randomized controlled trial. Strongest grade for intervention claims.

QuasiExperimental

Mendelian randomization, instrumental variables, regression discontinuity, natural experiments, etc.

Observational

Cohort, case-control, cross-sectional. Identifies association only without further design assumptions.

Theoretical

Computational simulation, theoretical model, mathematical proof.

Trait Implementations

impl Clone for CausalEvidenceGrade

fn clone(&self) -> CausalEvidenceGrade

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CausalEvidenceGrade

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CausalEvidenceGrade

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CausalEvidenceGrade

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
