Struct memcache_async::ascii::Protocol

pub struct Protocol<S> { /* private fields */ }

Implementations

impl<S> Protocol<S> where
    S: AsyncRead + AsyncWrite + Unpin, 

pub fn new(io: S) -> Self

Creates the ASCII protocol on a stream.

pub async fn get<K: Display>(&mut self, key: K) -> Result<Vec<u8>, Error>

Returns the value for given key as bytes. If the value doesn’t exist, ErrorKind::NotFound is returned.

pub async fn get_multi<K: AsRef<[u8]>>(
    &mut self,
    keys: &[K]
) -> Result<HashMap<String, Vec<u8>>, Error>

Returns values for multiple keys in a single call as a HashMap from keys to found values. If a key is not present in memcached it will be absent from returned map.

pub async fn get_prefix<K: Display>(
    &mut self,
    key_prefix: K,
    limit: Option<usize>
) -> Result<HashMap<String, Vec<u8>>, Error>

Get up to limit keys which match the given prefix. Returns a HashMap from keys to found values. This is not part of the Memcached standard, but some servers implement it nonetheless.

pub async fn add<K: Display>(
    &mut self,
    key: K,
    val: &[u8],
    expiration: u32
) -> Result<(), Error>

Add a key. If the value exists, ErrorKind::AlreadyExists is returned.

pub async fn set<K: Display>(
    &mut self,
    key: K,
    val: &[u8],
    expiration: u32
) -> Result<(), Error>

Set key to given value and don’t wait for response.

pub async fn delete<K: Display>(&mut self, key: K) -> Result<(), Error>

Delete a key and don’t wait for response.

pub async fn version(&mut self) -> Result<String, Error>

Return the version of the remote server.

pub async fn flush(&mut self) -> Result<(), Error>

Delete all keys from the cache.
