Enum Entity 

pub enum Entity<K, T> {
    Key(Key<K>),
    Data(Box<T>),
    None,
}

Enum for defining a simple entity that will hold a Key or the created/fetched data

Variants

Key(Key<K>)

Key of the entity

Data(Box<T>)

Created/Fetched data for the entity

None

For when you have no data to fill or null from database

Implementations

impl<K, T> Entity<K, T>

pub fn data(&self) -> Result<&T>

Returns the data if it exists and was fetched/created

pub fn data_mut(&mut self) -> Result<&mut T>

Returns the mutable data if it exists and was fetched/created

pub fn is_key(&self) -> bool

Is this a Key variant?

pub fn is_data(&self) -> bool

Is this a Data variant?

pub fn is_none(&self) -> bool

Is this a None variant?

Trait Implementations

impl<K: Clone, T: Clone> Clone for Entity<K, T>

fn clone(&self) -> Entity<K, T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug, T: Debug> Debug for Entity<K, T>

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

Formats the value using the given formatter.

impl<K, T> Default for Entity<K, T>

fn default() -> Entity<K, T>

Returns the “default value” for a type.

impl<'de, K, T> Deserialize<'de> for Entity<K, T>

where K: Deserialize<'de>, T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<K, T> From<T> for Entity<K, T>

fn from(entity: T) -> Self

Converts to this type from the input type.

impl<K, T> Keyed for Entity<K, T>

where T: Keyed<KeyType = K>,

type KeyType = K

The type of the Key

fn key(&self) -> Result<&Key<Self::KeyType>>

Returns the Key for the Entity

impl<K: PartialEq, T: PartialEq> PartialEq for Entity<K, T>

fn eq(&self, other: &Entity<K, T>) -> 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.

impl<K, T> Serialize for Entity<K, T>

where K: Serialize, T: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
