Modules

error

PostgresClient-related errors.

metrics

Implementation-specific metrics for the internal, pooled Postgres client.

Structs

Client

A pooled Postgres connection tagged with the IsolationLevel it was created under.

Manager

A deadpool managed::Manager wrapping deadpool_postgres::Manager. It applies a per-connection isolation level at creation and records that level on every Client it hands out.

PostgresClient

A Postgres client wrapper that uses deadpool as a connection pool.

PostgresClientConfig

Configuration for creating a PostgresClient.

Enums

IsolationLevel

The transaction isolation level applied to new connections.

Traits

PostgresClientKnobs

Configuration knobs for PostgresClient.

Type Aliases

Connection

A connection handed out by PostgresClient::get_connection. Dereferences to a Client, which additionally records the IsolationLevel the connection was created under.

IsolationLevelFn

Resolves the isolation level to apply to a connection. It is invoked once per connection creation, so a dyncfg-backed resolver lets a change take effect as the pool cycles connections.
