Simple No SQL interface that expose simple sync and async API to interact with the database.

Provided Associated Types

type Err = Error

Required Methods

fn new(uri: &str) -> Result<Self, Self::Err>

where Self: Sized,

create a new instance of the database with the URI provided.

The URI can be a http link or a simple disk path.

fn get(&self, key: &str) -> String

get the value with the key inside the database panic if the value if the look up fails.

fn put(&self, key: &str, value: &str)

put the value inside the database with the key panic is there is any error while communicating with the db.

fn opt_get(&self, key: &str) -> Result<String, Self::Err>

like the get API but return an error if the key is not present

fn opt_put(&self, key: &str, value: &str) -> Result<(), Self::Err>

like the put API bit return and error if this occurs.

fn contains(&self, key: &str) -> bool

check if the key is present inside the database

fn keys(&self) -> Vec<&'static str>

return the list of keys that are insert inside the database.
