Struct crux_kv::KeyValue

pub struct KeyValue<Ev> { /* private fields */ }

Implementations

impl<Ev> KeyValue<Ev>where Ev: 'static,

pub fn new(context: CapabilityContext<KeyValueOperation, Ev>) -> Self

pub fn read<F>(&self, key: &str, make_event: F)where F: Fn(KeyValueOutput) -> Ev + Send + Sync + 'static,

Read a value under key, will dispatch the event with a KeyValueOutput::Read(Option<Vec<u8>>) as payload

pub fn write<F>(&self, key: &str, value: Vec<u8>, make_event: F)where F: Fn(KeyValueOutput) -> Ev + Send + Sync + 'static,

Set key to be the provided value. Typically the bytes would be a value serialized/deserialized by the app.

Will dispatch the event with a KeyValueOutput::Write(bool) as payload
