sourcepub fn new(channel: Channel, db_name: AsciiValue, creds: C) -> Self
pub fn new(channel: Channel, db_name: AsciiValue, creds: C) -> Self
YdbConnection constructor
§Arguments
channel
- transport channel to database (can be make fromEndpoint
)db_name
- database name (you can get it from yandex cloud for example) inAsciiValue
formatcreds
- some object, that implementsCredentials
(e.g.String
)
§Examples
See self
sourcepub fn discovery(&mut self) -> DiscoveryServiceClient<&mut Self>
pub fn discovery(&mut self) -> DiscoveryServiceClient<&mut Self>
Creates discovery service client
§Examples
let mut conn = ydb_unofficial::YdbConnection::from_env();
let db_name = std::env::var("DB_NAME").unwrap();
use ydb_unofficial::generated::ydb::discovery::ListEndpointsRequest;
let endpoints_response = conn.discovery().list_endpoints(
ListEndpointsRequest{
database: db_name.into(),
..Default::default()
}
).await.unwrap();
// how you can parse response to invoke result with YdbResponseWithResult trait
use ydb_unofficial::YdbResponseWithResult;
let endpoints_result = endpoints_response.get_ref().result().unwrap();
assert!(endpoints_result.endpoints.len() > 0);
sourcepub async fn table(&mut self) -> Result<TableClientWithSession<'_, C>, YdbError>
pub async fn table(&mut self) -> Result<TableClientWithSession<'_, C>, YdbError>
Creates session and returns TableClientWithSession
§Examples
let mut conn = ydb_unofficial::YdbConnection::from_env();
let mut table_client = conn.table().await.unwrap();
use ydb_unofficial::generated::ydb::table::*;
let keep_alive_response = table_client.keep_alive(KeepAliveRequest::default()).await.unwrap();
//..some another code
pub fn table_if_ready(&mut self) -> Option<TableClientWithSession<'_, C>>
pub async fn close_session(&mut self) -> Result<(), YdbError>

fn map_err<F, Error>(self, f: F) -> MapErr<Self, F>

method. Read moresource§fn map_result<F, Response, Error>(self, f: F) -> MapResult<Self, F>
fn map_result<F, Response, Error>(self, f: F) -> MapResult<Self, F>

fails. Read moresource§fn map_request<F, NewRequest>(self, f: F) -> MapRequest<Self, F>
