Struct feattle::persist::NoPersistence

pub struct NoPersistence;

A mock implementation that does not store the information anywhere.

Trait Implementations

impl Clone for NoPersistence

fn clone(&self) -> NoPersistence

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for NoPersistence

impl Debug for NoPersistence

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

Formats the value using the given formatter.

impl PartialEq<NoPersistence> for NoPersistence

fn eq(&self, other: &NoPersistence) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Persist for NoPersistence

type Error = Error

fn save_current<'life0, 'life1, 'async_trait>(
    &'life0 self,
    _value: &'life1 CurrentValues
) -> Pin<Box<dyn Future<Output = Result<(), <NoPersistence as Persist>::Error>> + 'async_trait + Send>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    NoPersistence: 'async_trait, 

Save current state of all feattles.

fn load_current<'life0, 'async_trait>(
    &'life0 self
) -> Pin<Box<dyn Future<Output = Result<Option<CurrentValues>, <NoPersistence as Persist>::Error>> + 'async_trait + Send>> where
    'life0: 'async_trait,
    NoPersistence: 'async_trait, 

Load the current state of all feattles. With no previous state existed, Ok(None) should be returned.

fn save_history<'life0, 'life1, 'life2, 'async_trait>(
    &'life0 self,
    _key: &'life1 str,
    _value: &'life2 ValueHistory
) -> Pin<Box<dyn Future<Output = Result<(), <NoPersistence as Persist>::Error>> + 'async_trait + Send>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    'life2: 'async_trait,
    NoPersistence: 'async_trait, 

Save the full history of a single feattle.

fn load_history<'life0, 'life1, 'async_trait>(
    &'life0 self,
    _key: &'life1 str
) -> Pin<Box<dyn Future<Output = Result<Option<ValueHistory>, <NoPersistence as Persist>::Error>> + 'async_trait + Send>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    NoPersistence: 'async_trait, 

Load the full history of a single feattle. With the feattle has no history, Ok(None) should be returned.
