Implementations

impl MemcacheClient

pub async fn connect(addr: &str) -> Self

pub async fn set( &self, key: &str, value: &[u8], flags: u32, exptime: u32, ) -> Result<(), String>

pub async fn set_quietly(&self, key: &str, value: &[u8]) -> Result<(), String>

Set a key without waiting for a reply (hot path, fire-and-forget).

pub async fn set_multi<'a, I>( &self, items: I, flags: u32, exptime: u32, ) -> Result<(), String>

where I: IntoIterator<Item = (&'a str, &'a [u8])>,

pub async fn set_multi_quietly<'a, I>(&self, items: I) -> Result<(), String>

where I: IntoIterator<Item = (&'a str, &'a [u8])>,

Batch set using SETQ for all but the last key, and SET for the last key (waits for one response).

pub async fn get(&self, key: &str) -> Result<Option<Vec<u8>>, String>

pub async fn get_multi<'a, I>( &self, keys: I, ) -> Result<Vec<(String, Option<Vec<u8>>)>, String>

where I: IntoIterator<Item = &'a str>,

pub async fn delete(&self, key: &str) -> Result<(), String>

Delete a single key, waits for response.

pub async fn delete_quietly(&self, key: &str) -> Result<(), String>

Delete a single key, quietly (no response).

pub async fn delete_multi<'a, I>(&self, keys: I) -> Result<(), String>

where I: IntoIterator<Item = &'a str>,

Delete multiple keys, waits for response for each.

pub async fn delete_multi_quietly<'a, I>(&self, keys: I) -> Result<(), String>

where I: IntoIterator<Item = &'a str>,

Delete multiple keys, quietly (all but last as DELQ, last as DEL).

pub async fn incr( &self, key: &str, delta: u64, initial: u64, exptime: u32, ) -> Result<Option<u64>, String>

Increment a key by delta. Returns the new value or None if not found.

pub async fn decr( &self, key: &str, delta: u64, initial: u64, exptime: u32, ) -> Result<Option<u64>, String>

Decrement a key by delta. Returns the new value or None if not found.

pub async fn noop(&self) -> Result<(), String>

Send a NOOP command (useful for pipelining).
