Struct QuerySetSentinelKey 

pub struct QuerySetSentinelKey { /* private fields */ }

Sentinel for tracking all queries of a type.

Used by list_queries to track dependencies on the set of queries, rather than individual query values.

Implementations

impl QuerySetSentinelKey

pub fn new<Q: 'static>() -> Self

Create a new query set sentinel key.

pub fn query_type(&self) -> TypeId

Get the query type ID.

pub fn type_name(&self) -> &'static str

Get the type name for this query set sentinel.

Trait Implementations

impl Clone for QuerySetSentinelKey

fn clone(&self) -> QuerySetSentinelKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuerySetSentinelKey

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

Formats the value using the given formatter.

impl From<QuerySetSentinelKey> for FullCacheKey

fn from(key: QuerySetSentinelKey) -> Self

Converts to this type from the input type.

impl Hash for QuerySetSentinelKey

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 QuerySetSentinelKey

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