Struct ReadOnlyPrefixedState 

pub struct ReadOnlyPrefixedState<'a> { /* private fields */ }

A borrowed, read-only view of state that automatically prepends a prefix to all keys.

Unlike PrefixedState, this does not expose set() or remove() methods, making it suitable for computed/derived state that user code should not mutate.

Implementations

impl<'a> ReadOnlyPrefixedState<'a>

pub fn get<T: DeserializeOwned>(&self, key: &str) -> Option<T>

Get a value by key (with prefix applied).

pub fn get_raw(&self, key: &str) -> Option<Value>

Get a raw JSON value by key (with prefix applied).

pub fn with<F, R>(&self, key: &str, f: F) -> Option<R>

where F: FnOnce(&Value) -> R,

Zero-copy borrow a value by key (with prefix applied).

pub fn contains(&self, key: &str) -> bool

Check if a key exists (with prefix applied).

pub fn keys(&self) -> Vec<String>

Get all keys within this prefix scope (prefix stripped from results).
