Struct fuel_vm::storage::ContractsRawCode

pub struct ContractsRawCode;

The storage table for contract’s raw byte code.

Trait Implementations

impl Mappable for ContractsRawCode

type Key = <ContractsRawCode as Mappable>::OwnedKey

The key type is used during interaction with the storage. In most cases, it is the same as Self::OwnedKey.

type OwnedKey = ContractId

The owned type of the Key retrieving from the storage.

type OwnedValue = Contract

The owned type of the Value retrieving from the storage.

type Value = [u8]

The value type is used while setting the value to the storage. In most cases, it is the same as Self::OwnedValue, but it is without restriction and can be used for performance optimizations.

impl StorageInspect<ContractsRawCode> for MemoryStorage

type Error = Infallible

fn get(&self, key: &ContractId) -> Result<Option<Cow<'_, Contract>>, Infallible>

Retrieve Cow<Value> such as Key->Value.

fn contains_key(&self, key: &ContractId) -> Result<bool, Infallible>

Return true if there is a Key mapping to a value in the storage.

impl StorageMutate<ContractsRawCode> for MemoryStorage

fn insert( &mut self, key: &ContractId, value: &[u8] ) -> Result<Option<Contract>, Infallible>

Append Key->Value mapping to the storage.

fn remove(&mut self, key: &ContractId) -> Result<Option<Contract>, Infallible>

Remove Key->Value mapping from the storage.

impl StorageRead<ContractsRawCode> for MemoryStorage

fn read( &self, key: &ContractId, buf: &mut [u8] ) -> Result<Option<usize>, Self::Error>

Read the value stored at the given key into the provided buffer if the value exists.

fn read_alloc(&self, key: &ContractId) -> Result<Option<Vec<u8>>, Self::Error>

Same as read but allocates a new buffer and returns it.

impl StorageRead<ContractsRawCode> for PredicateStorage

fn read( &self, _key: &<ContractsRawCode as Mappable>::Key, _buf: &mut [u8] ) -> Result<Option<usize>, StorageUnavailable>

Read the value stored at the given key into the provided buffer if the value exists.

fn read_alloc( &self, _key: &<ContractsRawCode as Mappable>::Key ) -> Result<Option<Vec<u8>>, StorageUnavailable>

Same as read but allocates a new buffer and returns it.

impl StorageSize<ContractsRawCode> for MemoryStorage

fn size_of_value(&self, key: &ContractId) -> Result<Option<usize>, Infallible>

Return the number of bytes stored at this key.

impl StorageSize<ContractsRawCode> for PredicateStorage

fn size_of_value( &self, _key: &ContractId ) -> Result<Option<usize>, StorageUnavailable>

Return the number of bytes stored at this key.

impl StorageWrite<ContractsRawCode> for MemoryStorage

fn write(&mut self, key: &ContractId, buf: Vec<u8>) -> Result<usize, Infallible>

Write the value to the given key from the provided buffer.

fn replace( &mut self, key: &<ContractsRawCode as Mappable>::Key, buf: Vec<u8> ) -> Result<(usize, Option<Vec<u8>>), Self::Error>where Self: StorageSize<ContractsRawCode>,

Write the value to the given key from the provided buffer and return the previous value if it existed.

fn take( &mut self, key: &<ContractsRawCode as Mappable>::Key ) -> Result<Option<Vec<u8>>, Self::Error>

Removes a value from the storage and returning it without deserializing it.
