Functions ¶
func RegisterDatabaseClient ¶
RegisterDatabaseClient registers a database.Client with the injector. Prerequisite: database.ClientConfig must be registered (e.g. via databasecfg.RegisterClientConfig).
Types ¶
type Client ¶
type Client struct {
// contains filtered or unexported fields
}
Client is the primary database querying client.
func NewDatabaseClient ¶
func NewDatabaseClient(ctx context.Context, cfg database.ClientConfig, opts ...Option) (*Client, error)
NewDatabaseClient provides a new DataManager client. If a metrics provider is supplied via WithMetricsProvider, the DB driver will use it so SQL latency and other db.sql.* metrics are emitted (e.g. db_sql_latency_milliseconds_bucket in Prometheus).
func (*Client) CurrentTime ¶
CurrentTime reads the clock this client was built with.
func (*Client) Dialect ¶
Dialect reports the SQL dialect this client speaks, which is always dialect.SQLite.
func (*Client) Reader ¶
func (q *Client) Reader() database.SQLQueryExecutor
Reader returns a non-transactional executor for the read database.
func (*Client) RollbackTransaction ¶
func (q *Client) RollbackTransaction(ctx context.Context, tx database.SQLQueryExecutorAndTransactionManager)
RollbackTransaction rolls tx back, recording a failure on a span rather than returning it.
func (*Client) WithTransaction ¶
func (q *Client) WithTransaction(ctx context.Context, fn func(tx database.SQLQueryExecutor) error) error
WithTransaction runs fn inside a transaction on the write database, committing on a nil return and rolling back on error or panic. See database.RunInTransaction.
func (*Client) WriteDB ¶
WriteDB provides the database object. It satisfies database.RawAccess; prefer Writer and WithTransaction on the Client interface.
func (*Client) Writer ¶
func (q *Client) Writer() database.SQLQueryExecutor
Writer returns a non-transactional executor for the write database.
type Option ¶
type Option func(*options)
Option configures the database client this package constructs. The zero configuration works: an absent logger logs nowhere, an absent tracer provider traces nowhere, and an absent metrics provider emits no metrics.
func WithMetricsProvider ¶
WithMetricsProvider attaches a metrics provider; the DB driver uses it to emit SQL latency and other db.sql.* metrics.
func WithTracerProvider ¶
WithTracerProvider attaches a tracer provider, enabling spans on every database operation.
