Expand description

Struct containing ArangoDB connections and information to access the database, collections and documents

Implementations§

source§

impl DatabaseConnection

source

pub fn builder() -> DatabaseConnectionBuilder

Starts the builder for the database connection instance.

For default use with env var

let db_connection = DatabaseConnection::builder()
    // You can specify a host and credentials with this method.
    // Otherwise, the builder will look for the env vars: `DB_HOST`, `DB_NAME`, `DB_USER` and `DB_PASSWORD`.
    .with_credentials("http://localhost:8529", "db", "user", "password")
    // You can specify a authentication mode between `Basic` and `Jwt`
    // Otherwise the default value will be used (`Basic`).
    .with_auth_mode(AuthMode::Basic)
    // You can specify a schema path to initialize the database connection
    // Otherwise the env var `SCHEMA_PATH` or the default value `config/db/schema.yaml` will be used.
    .with_schema_path("config/db/schema.yaml")
    // If you prefer you can use your own custom schema
    .with_schema(DatabaseSchema::default())
    // The schema wil silently apply to the database, useful only if you don't use the CLI and migrations
    .apply_schema()
    // You then need to build the database connection
    .build()
    .await
    .unwrap();

You can also specify a custom DatabaseSchema using with_schema.

source

pub fn collections_names(&self) -> Vec<String>

retrieves a vector of all collection names from the database

source

pub async fn truncate(&self)

DESTRUCTIVE OPERATION

This will truncate all collections in the database, the collection will still exist but every document will be destryed.

Panics

If the truncate fails on some collection the method will panic, see the arangors_lite documentation on collection truncate.

source

pub async fn transactions_count(&self) -> Result<usize, Error>

Returns the number of currently running server-side transactions
