Struct Database 

pub struct Database { /* private fields */ }

Shared PostgreSQL database connection pool with schema initialization.

Data is isolated by app_id: each app gets its own PostgreSQL schema (CREATE SCHEMA IF NOT EXISTS "{app_id}"), and every connection obtained through conn() has search_path set to that schema. Two Database instances with different app_id values sharing the same physical database will not see each other’s tables.

Implementations

impl Database

pub async fn connect( connection_string: &str, app_id: &str, ) -> RustvelloResult<Self>

Create a new database from a connection string.

The connection string should be in the format: host=localhost user=postgres password=secret dbname=rustvello or a URI: postgres://user:pass@host/dbname

The app_id is used to create a dedicated PostgreSQL schema so that multiple applications can share the same database without interference.

Note: This method uses NoTls, so all data is sent in cleartext. For encrypted connections, use connect_tls() (requires the tls feature) or from_pool() with a custom pool configuration.

pub async fn connect_with_pool_size( connection_string: &str, app_id: &str, max_size: Option<usize>, ) -> RustvelloResult<Self>

Like connect() but with a configurable maximum pool size.

When max_size is None, deadpool’s default (CPU count × 4) is used.

pub async fn from_pool(pool: Pool, app_id: &str) -> RustvelloResult<Self>

Create a database from an existing deadpool pool.
