Enum ListPredKind 

#[non_exhaustive]
pub enum ListPredKind {
    Any,
    All,
    None,
    Single,
}

Discriminant for Expr::ListPredicate (cy-8x5, spec §19 row “List predicates”). Mirrors cyrs_hir::ListPredKind at the plan layer so the HIR is not leaked across the plan boundary.

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.

Any

ANY(v IN xs WHERE p) — at least one element matches.

All

ALL(v IN xs WHERE p) — every element matches.

None

NONE(v IN xs WHERE p) — no element matches.

Single

SINGLE(v IN xs WHERE p) — exactly one element matches.

Trait Implementations

impl Clone for ListPredKind

fn clone(&self) -> ListPredKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ListPredKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ListPredKind

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Hash for ListPredKind

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 ListPredKind

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

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Copy for ListPredKind

impl Eq for ListPredKind

impl StructuralPartialEq for ListPredKind
