Implementations

impl Host

pub fn get(&self, key: String) -> HandlerResult<GetResponse>

pub fn add(&self, key: String, value: i32) -> HandlerResult<AddResponse>

Add a given numeric value to a key

pub fn set(
    &self,
    key: String,
    value: String,
    expires: i32
) -> HandlerResult<SetResponse>

Sets the string value of a key

pub fn del(&self, key: String) -> HandlerResult<DelResponse>

Delete a key

pub fn clear(&self, key: String) -> HandlerResult<DelResponse>

Clear a list of its values. Depending on the provider implementation, this may delete the list entirely

pub fn range(
    &self,
    key: String,
    start: i32,
    stop: i32
) -> HandlerResult<ListRangeResponse>

Retrieve a range of values from a list. Depending on the provider implementation, start and stop may or may not be inclusive.

pub fn push(&self, key: String, value: String) -> HandlerResult<ListResponse>

Push a value onto a list

pub fn list_item_delete(
    &self,
    key: String,
    value: String
) -> HandlerResult<ListResponse>

Delete an item from a list

pub fn set_add(
    &self,
    key: String,
    value: String
) -> HandlerResult<SetOperationResponse>

Add an item into a set

pub fn set_remove(
    &self,
    key: String,
    value: String
) -> HandlerResult<SetOperationResponse>

Remove an item from a set

pub fn set_union(&self, keys: Vec<String>) -> HandlerResult<SetQueryResponse>

Perform and return a set union on a given list of keys

pub fn set_intersection(
    &self,
    keys: Vec<String>
) -> HandlerResult<SetQueryResponse>

Perform and return a set intersect on a given list of keys

pub fn set_query(&self, key: String) -> HandlerResult<SetQueryResponse>

Retrieve a list of items stored in a set

pub fn key_exists(&self, key: String) -> HandlerResult<GetResponse>

Indicates if a key exists
