Enum ArrayQuantifier 

pub enum ArrayQuantifier {
    Any,
    All,
    AllOrEmpty,
    None,
}

Quantifier for matching the members of an array-valued field.

Used by array object-scope blocks (field[any]: / field[all]:). This is deliberately distinct from the all value-list modifier (Modifier::All), which links several values of one field with AND. An array quantifier instead ranges over the members of an array-valued field.

Reference: proposed Sigma array-matching extension (sigma-specification Discussion #106).

Variants

Any

At least one array member must satisfy the nested detection.

All

Every array member must satisfy the nested detection, and the array must be non-empty.

AllOrEmpty

Every array member must satisfy the nested detection, but an empty or missing array also matches (the vacuously-true reading of All).

None

No array member satisfies the nested detection (the dual of Any). Matches an empty or missing array (vacuously, no member matches).

Trait Implementations

impl Clone for ArrayQuantifier

fn clone(&self) -> ArrayQuantifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ArrayQuantifier

impl Debug for ArrayQuantifier

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

Formats the value using the given formatter.

impl Display for ArrayQuantifier

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

Formats the value using the given formatter.

impl Eq for ArrayQuantifier

impl Hash for ArrayQuantifier

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 ArrayQuantifier

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
