Struct Client 

pub struct Client { /* private fields */ }

Client is an abstraction for grouping etcd operations and managing underlying network communications.

Implementations

impl Client

pub fn with_channel(channel: Channel, token: Option<String>) -> Self

Build clients from tonic Channel directly.

For advanced users, it provides the ability to control more details about the connection.

pub async fn connect_with_token( cfg: &ClientConfig, token: Option<String>, ) -> Result<Self>

pub async fn connect(cfg: ClientConfig) -> Result<Self>

Connects to etcd cluster and returns a client.

Errors

Will returns Err if failed to contact with given endpoints or authentication failed.
