Struct Disk

pub struct Disk { /* private fields */ }

Persist the data in the local filesystem, under a given directory.

At every save action, if the directory does not exist, it will be created.

Example

use std::sync::Arc;
use feattle_core::{feattles, Feattles};
use feattle_sync::Disk;

feattles! {
    struct MyToggles {
        a: bool,
    }
}

let my_toggles = MyToggles::new(Arc::new(Disk::new("some/local/directory")));

Implementations

impl Disk

pub fn new<P: Into<PathBuf>>(dir: P) -> Self

Trait Implementations

impl Clone for Disk

fn clone(&self) -> Disk

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Disk

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

Formats the value using the given formatter.

impl Persist for Disk

fn save_current<'life0, 'life1, 'async_trait>( &'life0 self, value: &'life1 CurrentValues, ) -> Pin<Box<dyn Future<Output = Result<(), BoxError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Save current state of all feattles.

fn load_current<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Option<CurrentValues>, BoxError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: '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<(), BoxError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: '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>, BoxError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

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