[−][src]Trait wascc_actor::KeyValueStore
Represents an abstraction around a client consuming a Key-Value store provided by the host
Required methods
fn get(&self, key: &str) -> Result<Option<String>>
Retrieves the value for a given key, returning the value and whether or not it existed.
fn set(&self, key: &str, value: &str, expires: Option<u32>) -> Result<()>
Sets the value for a given key
fn atomic_add(&self, key: &str, value: i32) -> Result<i32>
Performs an atomic add operation, returning the new value
fn list_add(&self, key: &str, item: &str) -> Result<usize>
Adds a string value to a list stored within a given key
fn list_del_item(&self, key: &str, item: &str) -> Result<usize>
Deletes all occurrences of an item in a list
fn del_key(&self, key: &str) -> Result<()>
Deletes the given key
fn list_range(
&self,
key: &str,
start: isize,
stop_inclusive: isize
) -> Result<Vec<String>>
&self,
key: &str,
start: isize,
stop_inclusive: isize
) -> Result<Vec<String>>
Requests a list of values contained within a given key
fn list_clear(&self, key: &str) -> Result<()>
Clears a list
fn set_add(&self, key: &str, value: &str) -> Result<usize>
Adds an item to a set
fn set_remove(&self, key: &str, value: &str) -> Result<usize>
Removes an item from a set
fn set_union(&self, keys: Vec<String>) -> Result<Vec<String>>
Returns the union of sets indicated by list of keys
fn set_intersect(&self, keys: Vec<String>) -> Result<Vec<String>>
Returns the intersection of all sets indicated by the list of keys
fn set_members(&self, key: &str) -> Result<Vec<String>>
Returns all members of a given set
fn exists(&self, key: &str) -> Result<bool>
Indicates whether or not a given key exists in the data store
