Struct ObjectKey 

pub struct ObjectKey { /* private fields */ }

Unique key for an object in the identity map.

Implementations

impl ObjectKey

pub fn from_model<M: Model + 'static>(obj: &M) -> Self

Create an object key from a model instance.

pub fn from_pk<M: Model + 'static>(pk: &[Value]) -> Self

Create an object key from type and primary key.

pub fn pk_hash(&self) -> u64

Get the primary key hash.

pub fn type_id(&self) -> TypeId

Get the type identifier.

Trait Implementations

impl Clone for ObjectKey

fn clone(&self) -> ObjectKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectKey

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

Formats the value using the given formatter.

impl Hash for ObjectKey

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 ObjectKey

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