Method GetString

environment.go:317–342

GetString returns value stored in the environment, casted to string. If value does not exist, or is not string, reports failure and returns empty string. Example: value := env.GetString("key")

(key string)

//
//	value := env.GetString("key")
func (e *Environment) GetString(key string) string {
	opChain := e.chain.enter("GetString(%q)", key)
	defer opChain.leave()

	e.mu.RLock()
	defer e.mu.RUnlock()

	value, ok := envValue(opChain, e.data, key)
	if !ok {
		return ""
	}

	casted, ok := value.(string)
	if !ok {
		opChain.fail(AssertionFailure{
			Type:   AssertType,
			Actual: &AssertionValue{value},
			Errors: []error{
				errors.New("expected: string value"),
			},
		})
		return ""
	}

	return casted
}

// GetBytes returns value stored in the environment, casted to []byte.
