Struct Lazy 

pub struct Lazy<T> { /* private fields */ }

Lazy-loaded model.

Implementations

impl<T> Lazy<T>

pub fn from_raw(cell: Cell) -> Self

Wraps the cell in a typed wrapper.

pub fn into_inner(self) -> Cell

Converts into the underlying cell.

pub fn inner(&self) -> &Cell

Returns the underlying cell.

pub fn cast_into<Q>(self) -> Lazy<Q>

where Q: EquivalentRepr<T>,

Converts into a lazy loader for an equivalent type.

pub fn cast_ref<Q>(&self) -> &Lazy<Q>

where Q: EquivalentRepr<T>,

Casts itself into a lazy loaded for an equivalent type.

pub fn serialize_repr_hash<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serializes only the root hash of the cell.

impl<T: Store> Lazy<T>

pub fn new(data: &T) -> Result<Self, Error>

Serializes the provided data and returns the typed wrapper around it.

pub fn set(&mut self, data: &T) -> Result<(), Error>

Updates the content with the provided data.

impl<'a, T: Load<'a> + 'a> Lazy<T>

pub fn load(&'a self) -> Result<T, Error>

Loads inner data from cell.

Trait Implementations

impl<T> AsRef<dyn CellImpl + Send + Sync> for Lazy<T>

fn as_ref(&self) -> &DynCell

Converts this type into a shared reference of the (usually inferred) input type.

impl<T> Clone for Lazy<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Lazy<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Lazy<T>

where T: Deserialize<'de> + Store,

fn deserialize<D>(deserializer: D) -> Result<Lazy<T>, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> ExactSize for Lazy<T>

fn exact_size(&self) -> Size

Exact size of the value when it is stored in a slice.

impl<'a, T> Load<'a> for Lazy<T>

fn load_from(slice: &mut CellSlice<'a>) -> Result<Self, Error>

Tries to load itself from a cell slice.

impl<T> PartialEq for Lazy<T>

fn eq(&self, other: &Self) -> 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<T> Serialize for Lazy<T>

where for<'a> T: Serialize + Load<'a>,

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<T> Store for Lazy<T>

fn store_into( &self, builder: &mut CellBuilder, _: &mut dyn CellContext, ) -> Result<(), Error>

Tries to store itself into the cell builder.

impl<T: WithAbiType> WithAbiType for Lazy<T>

fn abi_type() -> AbiType

Returns a corresponding ABI type.

impl<T> Eq for Lazy<T>
