Struct QueryId 

pub struct QueryId {
    pub query_type: TypeId,
    pub key_hash: u64,
}

A unique identifier for a query invocation.

Fields

query_type: TypeId

The type of query.

key_hash: u64

A hash of the query key.

Trait Implementations

impl Clone for QueryId

fn clone(&self) -> QueryId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryId

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

Formats the value using the given formatter.

impl Hash for QueryId

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 QueryId

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