func CheckMetadataKeyAndValueLength

func CheckMetadataKeyAndValueLength(limit int, metadata map[string]any) error

CheckMetadataKeyAndValueLength check the length of key and value to a limit pass by on field limit

func Contains

func Contains[T comparable](slice []T, item T) bool

Contains checks if an item is in a slice. This function uses type parameters to work with any slice type.

func EnsureConfigFromEnvVars

func EnsureConfigFromEnvVars(s any) any

func GetenvBoolOrDefault

func GetenvBoolOrDefault(key string, defaultValue bool) bool

GetenvBoolOrDefault returns the value of os.Getenv(key string) value as bool or defaultValue if error Is the environment variable (key) is not defined, it returns the given defaultValue If the environment variable (key) is not a valid bool format, it returns the given defaultValue If any error occurring during bool parse, it returns the given defaultValue.

func GetenvIntOrDefault

func GetenvIntOrDefault(key string, defaultValue int64) int64

GetenvIntOrDefault returns the value of os.Getenv(key string) value as int or defaultValue if error If the environment variable (key) is not defined, it returns the given defaultValue If the environment variable (key) is not a valid int format, it returns the given defaultValue If any error occurring during int parse, it returns the given defaultValue.

func GetenvOrDefault

func GetenvOrDefault(key string, defaultValue string) string

GetenvOrDefault encapsulate built-in os.Getenv behavior but if key is not present it returns the defaultValue.

func IsNilOrEmpty

func IsNilOrEmpty(s *string) bool

IsNilOrEmpty returns a boolean indicating if a *string is nil or empty. It's use TrimSpace so, a string " " and "" and "null" and "nil" will be considered empty

func SafeIntToUint64(val int) uint64

SafeIntToUint64 safe mode to converter int to uint64

func SetConfigFromEnvVars

func SetConfigFromEnvVars(s any) error

SetConfigFromEnvVars builds a struct by setting it fields values using the "var" tag Constraints: s any - must be an initialized pointer Supported types: String, Boolean, Int, Int8, Int16, Int32 and Int64.

func ValidateCountryAddress

func ValidateCountryAddress(country string) error

ValidateCountryAddress validate if country in object address contains in countries list using ISO 3166-1 alpha-2

func ValidateCurrency

func ValidateCurrency(code string) error

ValidateCurrency validate if code contains in currencies list using ISO 4217

func ValidateType

func ValidateType(t string) error

ValidateType validate type values of currencies

Types

type App

type App interface {
	Run(launcher *Launcher) error
}

App represents an application that will run as a deployable component. It's an entrypoint at main.go.

type EntityConflictError struct {
	EntityType string
	Title      string
	Message    string
	Code       string
	Err        error
}

EntityConflictError records an error indicating an entity already exists in some repository You can use it to representing a Database conflict, cache or any other repository.

func (EntityConflictError) Error

func (e EntityConflictError) Error() string

Error implements the error interface.

func (EntityConflictError) Unwrap

func (e EntityConflictError) Unwrap() error

Unwrap implements the error interface introduced in Go 1.13 to unwrap the internal error.

type EntityNotFoundError

type EntityNotFoundError struct {
	EntityType string
	Title      string
	Message    string
	Code       string
	Err        error
}

EntityNotFoundError records an error indicating an entity was not found in any case that caused it. You can use it to representing a Database not found, cache not found or any other repository.

func NewEntityNotFoundError

func NewEntityNotFoundError(entityType string) EntityNotFoundError

NewEntityNotFoundError creates an instance of EntityNotFoundError.

func WrapEntityNotFoundError

func WrapEntityNotFoundError(entityType string, err error) EntityNotFoundError
