Struct diem_secure_storage::InMemoryStorage

pub struct InMemoryStorage { /* fields omitted */ }

InMemoryStorage represents a key value store that is purely in memory and intended for single threads (or must be wrapped by a Arc<RwLock<>>). This provides no permission checks and simply is a proof of concept to unblock building of applications without more complex data stores. Internally, it retains all data, which means that it must make copies of all key material which violates the Diem code base. It violates it because the anticipation is that data stores would securely handle key material. This should not be used in production.

Trait Implementations

impl Default for InMemoryStorage

fn default() -> InMemoryStorage

Returns the “default value” for a type.

impl From<InMemoryStorage> for Storage

fn from(v: InMemoryStorage) -> Storage

Performs the conversion.

impl KVStorage for InMemoryStorage

fn available(&self) -> Result<(), Error>

Returns an error if the backend service is not online and available.

fn get<V: DeserializeOwned>(&self, key: &str) -> Result<GetResponse<V>, Error>

Retrieves a value from storage and fails if the backend is unavailable or the process has invalid permissions.

fn set<V: Serialize>(&mut self, key: &str, value: V) -> Result<(), Error>

Sets a value in storage and fails if the backend is unavailable or the process has invalid permissions.

fn reset_and_clear(&mut self) -> Result<(), Error>

Resets and clears all data held in the storage engine. Note: this should only be exposed and used for testing. Resetting the storage engine is not something that should be supported in production.

impl TryInto<InMemoryStorage> for Storage

type Error = &'static str

The type returned in the event of a conversion error.

fn try_into(
    self
) -> Result<InMemoryStorage, <Self as TryInto<InMemoryStorage>>::Error>

Performs the conversion.
