Struct FactKey 

pub struct FactKey {
    pub fact_type: String,
    pub field: Option<String>,
    pub pattern: String,
}

Canonical key for identifying a fact (type + field values)

Fields

fact_type: String

Fact type (e.g., “User”, “Order”)

field: Option<String>

Field name if specific field query (e.g., “User.Score”)

pattern: String

Expected value for field (e.g., “Score >= 80”)

Implementations

impl FactKey

pub fn from_pattern(pattern: &str) -> Self

Create a new fact key from a pattern string

pub fn new(fact_type: String, field: Option<String>, pattern: String) -> Self

Create from explicit components

Trait Implementations

impl Clone for FactKey

fn clone(&self) -> FactKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FactKey

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

Formats the value using the given formatter.

impl Hash for FactKey

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 FactKey

fn eq(&self, other: &FactKey) -> 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.
