Enum DropKind 

pub enum DropKind {
    SlotLocal,
    Unimplemented,
    Nonstandard,
    Cascade,
    Unclassified,
}

Why an entity was dropped before it could enter the model. SlotLocal = a slot value could not be normalized to standard (req-ref<-$, int<-fractional). Unimplemented = the entity type is outside the generated closure (not yet modeled, or an unknown/non-schema name). Nonstandard = a known closure type sits in a SELECT slot that does not admit it (schema violation). Cascade = a referrer whose target was dropped/dangling. Unclassified = the generated read could not consume the entity’s own attributes (off-kind scalar, bad enum token, short arity, …) and no policy layer (normalize / drop_pass) classified it — a frontier signal: investigate and absorb via normalize or nonstd_ref.

Trait Implementations

impl Clone for DropKind

fn clone(&self) -> DropKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DropKind

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

Formats the value using the given formatter.

impl Eq for DropKind

impl Ord for DropKind

fn cmp(&self, other: &DropKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DropKind

fn eq(&self, other: &DropKind) -> 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 PartialOrd for DropKind

fn partial_cmp(&self, other: &DropKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
