Struct actix_storage_sled::SledStore

pub struct SledStore { /* fields omitted */ }

A simple implementation of Store based on Sled

This provider doesn't support key expiration thus Storage will return errors when trying to use methods that require expiration functionality if there is no expiry provided.

Example

use actix_storage::Storage;
use actix_storage_sled::SledStore;
use actix_web::{App, HttpServer};

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    let db = SledStore::new().expect("Error opening the database");
    let storage = Storage::build().store(db).finish();
    let server = HttpServer::new(move || {
        App::new()
            .data(storage.clone())
    });
    server.bind("localhost:5000")?.run().await
}

impl Store for SledStore

fn set<'life0, 'async_trait>(
    &'life0 self,
    key: Arc<[u8]>,
    value: Arc<[u8]>
) -> Pin<Box<dyn Future<Output = StorageResult<()>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Set a key-value pair, if the key already exist, value should be overwritten

fn get<'life0, 'async_trait>(
    &'life0 self,
    key: Arc<[u8]>
) -> Pin<Box<dyn Future<Output = StorageResult<Option<Arc<[u8]>>>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Get a value for specified key, it should result in None if the value does not exist

fn delete<'life0, 'async_trait>(
    &'life0 self,
    key: Arc<[u8]>
) -> Pin<Box<dyn Future<Output = StorageResult<()>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Delete the key from storage, if the key doesn't exist, it shouldn't return an error

fn contains_key<'life0, 'async_trait>(
    &'life0 self,
    key: Arc<[u8]>
) -> Pin<Box<dyn Future<Output = StorageResult<bool>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Check if key exist in storage
