State store request.

Variants

Save

Stores a piece of state to storage.

Fields of Save

key: Cow<'static, [u8]>

Key to store under.

data: Vec<u8>

Value to store, already serialized.

responder: Responder<()>

Notification when storing is complete.

Load

Loads a piece of state from storage.

Fields of Load

key: Cow<'static, [u8]>

Key to load from.

responder: Responder<Option<Vec<u8>>>

Responder for value, if found, returning the previously passed in serialization form.

Trait Implementations

impl DataSize for StateStoreRequest

pub const IS_DYNAMIC: bool

If true, the type has a heap size that can vary at runtime, depending on the actual value.

pub const STATIC_HEAP_SIZE: usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

pub fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for StateStoreRequest

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

Formats the value using the given formatter.

impl Display for StateStoreRequest

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

Formats the value using the given formatter.

impl From<StateStoreRequest> for Event

pub fn from(original: StateStoreRequest) -> Event

Performs the conversion.

impl Serialize for StateStoreRequest

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

Serialize this value into the given Serde serializer.
