Struct QueryKey 

pub struct QueryKey {
    pub predicate_name: String,
    pub ground_args: Vec<GroundArg>,
}

Query key for cache lookups

Fields

predicate_name: String

Predicate name

ground_args: Vec<GroundArg>

Ground arguments (for filtering)

Implementations

impl QueryKey

pub fn from_predicate(pred: &Predicate) -> Self

Create a query key from a predicate

Trait Implementations

impl Clone for QueryKey

fn clone(&self) -> QueryKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryKey

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

Formats the value using the given formatter.

impl Hash for QueryKey

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 QueryKey

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