Struct etcd_client::KvClient

#[repr(transparent)]
pub struct KvClient { /* fields omitted */ }

Client for KV operations.

Implementations

impl KvClient

pub async fn put(
    &mut self,
    key: impl Into<Vec<u8>>,
    value: impl Into<Vec<u8>>,
    options: Option<PutOptions>
) -> Result<PutResponse, Error>

Puts the given key into the key-value store. A put request increments the revision of the key-value store and generates one event in the event history.

pub async fn get(
    &mut self,
    key: impl Into<Vec<u8>>,
    options: Option<GetOptions>
) -> Result<GetResponse, Error>

Gets the key or a range of keys from the store.

pub async fn delete(
    &mut self,
    key: impl Into<Vec<u8>>,
    options: Option<DeleteOptions>
) -> Result<DeleteResponse, Error>

Deletes the given key or a range of keys from the key-value store.

pub async fn compact(
    &mut self,
    revision: i64,
    options: Option<CompactionOptions>
) -> Result<CompactionResponse, Error>

Compacts the event history in the etcd key-value store. The key-value store should be periodically compacted or the event history will continue to grow indefinitely.

pub async fn txn(&mut self, txn: Txn) -> Result<TxnResponse, Error>

Processes multiple operations in a single transaction. A txn request increments the revision of the key-value store and generates events with the same revision for every completed operation. It is not allowed to modify the same key several times within one txn.

Trait Implementations

impl Clone for KvClient

fn clone(&self) -> KvClient

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
