Struct IdentityStub

pub struct IdentityStub { /* private fields */ }

A identity stub is what we actually commit in the repository.

This is an almost empty Identity, holding only the Id. When a normal Identity is serialized into JSON, only the Id is serialized. All the other data is stored in git as a normal Entity.

Thus, when the JSON representation is deserialized, an IdentityStub is used instead, allowing us to lazy load the proper Identity later.

Implementations

impl IdentityStub

pub fn id(&self) -> EntityId<Identity>

Access the id of this IdentityStub.

pub fn resolve(self, replica: &Replica) -> Result<Identity, Error<Identity>>

Turn this IdentityStub into a full Identity.

This is a convenience wrapper around:

replica.get::<Identity>(stub.id())

Errors

When the replica.get function would error.

impl IdentityStub

pub fn as_value(&self) -> Value<'_>

Turn this IdentityStub into it’s JSON value representation.

pub fn from_value(value: &Value<'_, '_, '_>) -> Result<Self, Error>

Try to parse this IdentityStub from it’s JSON value representation.

Errors

If the value was did not actually represent an IdentityStub.

Trait Implementations

impl Clone for IdentityStub

fn clone(&self) -> IdentityStub

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IdentityStub

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IdentityStub

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for IdentityStub

fn cmp(&self, other: &IdentityStub) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for IdentityStub

fn eq(&self, other: &IdentityStub) -> 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 PartialOrd for IdentityStub

fn partial_cmp(&self, other: &IdentityStub) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for IdentityStub

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
