func LoadEnv ¶

func LoadEnv[T any](value string, fallback T, parser func(string) (T, error)) T

LoadEnv cast an environment variable to a native Go type, using the provided Parser function. If parsing fails, the fallback value is returned.

func Must ¶

func Must[T any](value T, err error) T

Must automatically panics if the error is not nil.

func MustUnmarshal ¶

func MustUnmarshal[T any](unmarshal func([]byte, any) error, src []byte) T

MustUnmarshal is a utility function that panics if the unmarshal operation fails.

func SliceParser ¶

func SliceParser[T any](parser func(string) (T, error)) func(string) ([]T, error)

SliceParser is a parsing function for LoadEnv, that returns a slice of values of type T. The parser accepts a sub-parser to define the type of T.

func StringParser ¶

func StringParser(value string) (string, error)

StringParser is a parsing function for LoadEnv, that returns the string content of the variable, as-is.

func TimeParser ¶

func TimeParser(value string) (time.Time, error)
