Represents a key-value store

Implementations§

Source§

impl Store

Source

pub fn new(connection: &str) -> Result<Store, Box<dyn Error>>

Returns a new yocto store

§Arguments
  • connection - A string slice that holds the endpoint of the yocto server
Source

pub fn get(&self, key: &str) -> Result<Option<String>, Box<dyn Error>>

Locates the given key inside the database and returns an Ok with the corresponding value if existing or an None if not.

§Arguments
  • key - A string slice that holds the key to look up
Source

pub fn insert( &self, key: &str, value: &str, ) -> Result<Option<String>, Box<dyn Error>>

Inserts a value for a specified key. Returns the old value if existent.

§Arguments
  • key - A string slice that holds the key to insert the value for
  • value - The value to insert
Source

pub fn remove(&self, key: &str) -> Result<Option<String>, Box<dyn Error>>

Removes the value corresponding to a key. Returns Err if key is not found.

§Arguments
  • key - A string slice that holds the key to delete the value for
Source

pub fn clear(&self) -> Result<Option<String>, Box<dyn Error>>

Removes all key-value pairs from the database
