Struct Session 

pub struct Session;

Zero-sized session handle — all operations access thread-local state.

Obtained via cf::session(). Methods are sync because they operate on the in-memory cache loaded by the async session() call.

Implementations

impl Session

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

Get a typed value from the session.

Returns Ok(None) if the key is not present.

Errors

Returns CfError if deserialization fails.

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

Set a value in the session.

The value is stored in the in-memory cache and flushed to the backend when the response is finalized.

Errors

Returns CfError if serialization fails.

pub fn remove(&self, key: &str)

Remove a key from the session.

pub fn destroy(&self)

Destroy the session — deletes backend data and clears the cookie.

pub fn is_empty(&self) -> bool

Returns true if the session has no data.

pub fn is_new(&self) -> bool

Returns true if this is a new session (no existing cookie was found).
