Struct SparseRef

pub struct SparseRef<S> { /* private fields */ }

An owned dynamic ref

SparseRef will render dynamically the pointed value.

It uses a SparseState to render itself in order to limit the IO calls at a minimum. It will deserialize into the desired type.

If the SparseStateFile used to render the object changes, SparseRef will deserialize it again in order to always be up to date.

Implementations

impl<S> SparseRef<S>

pub fn val(&self) -> &Box<SparsePointedValue<S>>

The value deserialized value, if any

pub fn utils(&self) -> &SparseMetadata

Metadata about the pointer

Trait Implementations

impl<S: Clone> Clone for SparseRef<S>

fn clone(&self) -> SparseRef<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for SparseRef<S>

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

Formats the value using the given formatter.

impl<'de, S> Deserialize<'de> for SparseRef<S>

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<S: PartialEq> PartialEq for SparseRef<S>

fn eq(&self, other: &SparseRef<S>) -> 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<S> Serialize for SparseRef<S>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<S> Sparsable for SparseRef<S>

where S: DeserializeOwned + Serialize + SparsableTrait,

fn sparse_init( &mut self, state: &mut SparseState, metadata: &SparseMetadata, depth: u32, ) -> Result<(), SparseError>

Initialize recusively a Sparsable pointer

fn sparse_updt<'a>( &mut self, state: &mut SparseState, metadata: &SparseMetadata, depth: u32, ) -> Result<(), SparseError>

Update recusively a Sparsable pointer

fn check_depth(&self, depth: u32) -> Result<(), SparseError>

Check if the current depth isn’t too much. This is the cyclic pointer protection mechanism

impl<S> SparsePointer<S> for SparseRef<S>

where S: DeserializeOwned + Serialize + SparsableTrait,

fn check_version<'a>( &'a self, state: &'a SparseState, ) -> Result<(), SparseError>

Check if the inner value is outdated

fn get(&self) -> Result<SparseValue<'_, S>, SparseError>

Get the inner value of the pointer

fn get_mut( &mut self, state_cell: Rc<RefCell<SparseState>>, ) -> Result<SparseValueMut<'_, S>, SparseError>

Get the inner value of the pointer (mutable)

fn self_reset( &mut self, state: &mut SparseState, metadata: &SparseMetadata, depth: u32, ) -> Result<(), SparseError>

Reset the inner value and parse it again from the state
