type CustomTypeFunc 

type CustomTypeFunc struct {

A CustomTypeFunc allows you to convert one type to another type before validation. This allows you to validate custom types with the built-in functions for, e.g., integers or strings.

type CustomValidator 

type CustomValidator struct {
	Name      string
	Validator validator.Func
}

A CustomValidator allows you to validate single fields with custom rules. If you need to validate a whole struct, you need to use a StructValidator. See https://github.com/go-playground/validator/issues/470 for more details.

}

Settings structure for an API server.

type StructValidator 

type StructValidator struct {
	Struct    interface{}
	Validator validator.StructLevelFunc
}

A StructValidator validates every instance of a struct type with the given validation. It is a little bit unfortunate because you now can't have different validation rules for a struct at different places.

type TimeoutSettings 

type TimeoutSettings struct {
	// You need to give at least 1s as timeout.
	// Read timeout is the maximum duration for reading the entire request, including the body.
	Read time.Duration `cfg:"read" default:"60s" validate:"min=1000000000"`
	// Write timeout is the maximum duration before timing out writes of the response.

	// Idle timeout is the maximum amount of time to wait for the next request when keep-alives are enabled

}

TimeoutSettings configures IO timeouts.

type ValidateAlias
