Types

type Config

type Config struct {
	// contains filtered or unexported fields
}

Config - config

type PingConnectionError

type PingConnectionError struct {
	Err error
}

PingConnectionError - error ping connection

func (*PingConnectionError) Error

func (e *PingConnectionError) Error() string

type Store

type Store struct {
	// contains filtered or unexported fields
}

Store implementation of db interface

func New

func New(tracer trace.TracerProvider, metrics *metric.MeterProvider) *Store

New return new instance of Store

func (*Store) GetConn

func (s *Store) GetConn() any

GetConn - get connect

func (*Store) Init

func (s *Store) Init(ctx context.Context) error

Init - initialize

type StoreError

type StoreError struct {
	Op      string
	Err     error
	Details string
}

StoreError is a custom error type for Store operations with added details.

func (*StoreError) Error

func (e *StoreError) Error() string

Error implements the error interface.

func (*StoreError) Unwrap

func (e *StoreError) Unwrap() error

Unwrap allows errors.Is and errors.As to work with StoreError.

type Tracer

type Tracer struct {
	trace.TracerProvider
}

func (*Tracer) TraceQueryEnd

func (*Tracer) TraceQueryEnd(ctx context.Context, _ *pgx.Conn, data pgx.TraceQueryEndData)

func (*Tracer) TraceQueryStart
