Struct StateStore 

pub struct StateStore { /* private fields */ }

Persistent key-value store scoped to a WASM producer (per route endpoint).

Each route endpoint using a WASM component gets its own independent state store. If two routes use the same .wasm file, they maintain separate state. Owned by WasmProducer and passed to WasmRuntime when creating host state.

Implementations

impl StateStore

pub fn new() -> Self

pub fn with_limits( max_entries: usize, max_key_bytes: usize, max_value_bytes: usize, ) -> Self

Build a StateStore with explicit bounds on entry count, key length, and value length. store rejects writes that exceed any of these limits.

pub fn store(&self, key: &str, value: &str) -> Result<(), String>

pub fn load(&self, key: &str) -> Result<Option<String>, String>

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

Trait Implementations

impl Clone for StateStore

fn clone(&self) -> StateStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateStore

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

Formats the value using the given formatter.

impl Default for StateStore

fn default() -> Self

Returns the “default value” for a type.
