Enum sppparse::SparseSelector

pub enum SparseSelector<T> {
    Ref(SparseRefRaw<T>),
    Obj(SparsePointedValue<T>),
    Null,
}

An owned selector between a raw object, a raw pointer or an owned pointer

Use this enum in your structure when allowing either a pointer or the value directly.

The SparseSelector allows to switch between a raw, unparsed pointer to a parsed pointer resolved at initialization.

Variants

Ref(SparseRefRaw<T>)

A deserialized JSON pointer contained the pointed value from the local or distant file

Obj(SparsePointedValue<T>)

The object included in the original document

Null

A default value that should not be present once the SparseRoot document has been initialized.

Trait Implementations

impl<T: Clone> Clone for SparseSelector<T>

fn clone(&self) -> SparseSelector<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for SparseSelector<T>

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

Formats the value using the given formatter.

impl<T> Default for SparseSelector<T> where
    T: Any + DeserializeOwned + Serialize + SparsableTrait, 

fn default() -> Self

Returns the "default value" for a type.

impl<'de, T> Deserialize<'de> for SparseSelector<T> where
    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<T: PartialEq> PartialEq<SparseSelector<T>> for SparseSelector<T>

fn eq(&self, other: &SparseSelector<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &SparseSelector<T>) -> bool

This method tests for !=.

impl<T> Serialize for SparseSelector<T> where
    T: Serialize, 

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

Serialize this value into the given Serde serializer.

impl<T> Sparsable for SparseSelector<T> where
    T: Any + DeserializeOwned + Serialize + SparsableTrait, 

fn sparse_init<'a>(
    &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<T> SparsePointer<T> for SparseSelector<T> where
    T: Any + 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<'_, T>, SparseError>

Get the inner value of the pointer

fn get_mut(
    &mut self,
    root: Rc<RefCell<SparseState>>
) -> Result<SparseValueMut<'_, T>, 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
