Struct State 

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

A key’s state, as a handler sees it.

Implementations

impl State<'_>

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

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

The value’s JSON as recorded.

pub fn set<T: Serialize>(&self, key: &str, value: &T) -> Result<()>

Sets key (null clears it). Only an exclusive handler may.

pub fn set_raw(&self, key: &str, json: Payload) -> Result<()>

pub fn clear(&self, key: &str) -> Result<()>

pub fn clear_all(&self) -> Result<()>

Clears every key.

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

The keys that hold a value, sorted.
