Struct Config

pub struct Config { /* private fields */ }

Configuration for building a Client.

Example

use spanner_rs::Config;
#[tokio::main]
let mut client = Config::builder()
    .project("my-gcp-project")
    .instance("my-spanner-instance")
    .database("my-database")
    .connect()
    .await?;

Implementations

impl Config

pub fn builder() -> ConfigBuilder

Returns a new ConfigBuilder for configuring a new client.

pub async fn connect(self) -> Result<Client, Error>

Connect to Cloud Spanner and return a new Client.

Example

use spanner_rs::Config;
#[tokio::main]
let mut client = Config::builder()
    .project("my-gcp-project")
    .instance("my-spanner-instance")
    .database("my-database")
    .connect()
    .await?;

Authentication

Authentication uses the gcp_auth crate which supports several authentication methods. In a typical production environment, nothing needs to be programatically provided during configuration as credentials are normally obtained from the environment (i.e.: GOOGLE_APPLICATION_CREDENTIALS).

Similarly, for local development, authentication will transparently delegate to the gcloud command line tool.

Trait Implementations

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
