Struct PostgresSessionStorage 

pub struct PostgresSessionStorage { /* private fields */ }

PostgreSQL-backed SessionStorage implementation.

Note: the sessions table stores ids as UUID, so Session::id must be a valid UUID string - other values fail at runtime with a cast error.

Sessions are saved with last-write-wins semantics: there is no optimistic locking, so avoid running the same session concurrently from multiple workers (the later save silently overwrites the earlier one).

Implementations

impl PostgresSessionStorage

pub async fn connect(database_url: &str) -> Result<Self>

Connect with default pool settings (5 max connections) and run the schema migration. Use PostgresSessionStorage::with_pool for custom pool configuration.

pub async fn with_pool(pool: Pool<Postgres>) -> Result<Self>

Build the storage from a pre-configured pool (custom connection limits, timeouts, etc.) and run the schema migration.
