Struct StorageKey

pub struct StorageKey { /* private fields */ }

The key type suitable for use in Storage::get and other getter methods of Storage. Cheaply-clonable.

Implementations

impl StorageKey

pub fn key(&self) -> Arc<Vec<u8>>

Returns a new Arc reference to the bytes of this key.

pub fn to_cache_key(&self) -> CacheKey

Converts this key into a CacheKey via cloning.

pub fn into_cache_key(self) -> CacheKey

Converts this key into a CacheKey.

impl StorageKey

pub fn new<K, Q, KC>(prefix: &Prefix, key: &Q, codec: &KC) -> Self

where KC: EncodeKeyLike<Q, K>, Q: ?Sized,

Creates a new StorageKey that combines a prefix and a key.

pub fn singleton(prefix: &Prefix) -> Self

Creates a new StorageKey that combines a prefix and a key.

Trait Implementations

impl AsRef<Vec<u8>> for StorageKey

fn as_ref(&self) -> &Vec<u8>

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

impl BorshDeserialize for StorageKey

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 StorageKey

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 StorageKey

fn clone(&self) -> StorageKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StorageKey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for StorageKey

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

Formats the value using the given formatter.

impl From<&str> for StorageKey

fn from(key: &str) -> Self

Converts to this type from the input type.

impl From<CacheKey> for StorageKey

fn from(cache_key: CacheKey) -> Self

Converts to this type from the input type.

impl PartialEq for StorageKey

fn eq(&self, other: &StorageKey) -> 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 StorageKey

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
