Implementations

impl Databases

pub fn new(writing: DatabaseConnection) -> Self

A single-database setup (all queries hit writing).

pub fn with_reading(self, reading: DatabaseConnection) -> Self

Add a read replica; reads then route to it.

pub fn has_replica(&self) -> bool

Whether a read replica is configured.

pub fn connection(&self, role: Role) -> &DatabaseConnection

The connection for role — reads fall back to the writer without a replica.

pub fn writing(&self) -> &DatabaseConnection

The writing connection.

pub fn reading(&self) -> &DatabaseConnection

The reading connection (falls back to the writer).
