Struct StorageValue

pub struct StorageValue { /* private fields */ }

A serialized value suitable for storing. Internally uses an Arc<Vec<u8>> for cheap cloning.

Implementations

impl StorageValue

pub fn new<V, VC>(value: &V, codec: &VC) -> Self

where VC: StateValueCodec<V>,

Create a new storage value by serializing the input with the given codec.

pub fn value(&self) -> &[u8]

Get the bytes of this value.

pub fn into_cache_value(self) -> CacheValue

Convert this value into a CacheValue.

Trait Implementations

impl BorshDeserialize for StorageValue

where Arc<Vec<u8>>: BorshDeserialize,

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for StorageValue

where Arc<Vec<u8>>: BorshSerialize,

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for StorageValue

fn clone(&self) -> StorageValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageValue

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

Formats the value using the given formatter.

impl Default for StorageValue

fn default() -> StorageValue

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StorageValue

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&str> for StorageValue

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<CacheValue> for StorageValue

fn from(cache_value: CacheValue) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for StorageValue

fn from(value: Vec<u8>) -> Self

Converts to this type from the input type.

impl PartialEq for StorageValue

fn eq(&self, other: &StorageValue) -> 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 Serialize for StorageValue

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for StorageValue
