Trait SessionExt 

pub trait SessionExt {
    // Required methods
    fn get_by_key<T: DeserializeOwned>(
        &self,
        key: SessionKey<T>,
    ) -> Result<Option<T>, SessionGetError>;

    fn remove_by_key<T: DeserializeOwned>(
        &self,
        key: SessionKey<T>,
    ) -> Result<Option<T>, String>;
}

An extension trait for actix_session::session that provides a safer alternative to session::get, session::insert, session::remove methods. This trait is implemented for actix_session::session and provides methods that take SessionKey<T> instead of raw keys.

Required Methods

fn get_by_key<T: DeserializeOwned>( &self, key: SessionKey<T>, ) -> Result<Option<T>, SessionGetError>

Get a value from the session by key.

Errors

It returns an error if the value is not found or if the value is not of the expected type.

fn insert_by_key<T: Serialize>( &self, key: SessionKey<T>, value: T, ) -> Result<(), SessionInsertError>

Insert a value into the session by key.

Errors

It returns an error if the value cannot be serialized.

fn remove_by_key<T: DeserializeOwned>( &self, key: SessionKey<T>, ) -> Result<Option<T>, String>

Remove a value from the session by key.

Errors

It returns an error if the value cannot be deserialized.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
