	kernel.ServiceStage
	// contains filtered or unexported fields
}

type CompressionExcludeSettings

type CompressionExcludeSettings struct {
	Extension []string `cfg:"extension"`
	Path      []string `cfg:"path"`
	PathRegex []string `cfg:"path_regex"`
}

CompressionExcludeSettings allow enabling of gzip support.

type CompressionSettings

type CompressionSettings struct {
	Level         string `cfg:"level" default:"default" validate:"oneof=none default best fast 0 1 2 3 4 5 6 7 8 9"`

	// Exclude files by path, extension, or regular expression from being considered for compression. Useful if you are serving a format unknown to Gosoline.
	Exclude CompressionExcludeSettings `cfg:"exclude"`

CompressionSettings control gzip support for requests and responses. By default, compressed requests are accepted and compressed responses are returned (if accepted by the client).

type CustomTypeFunc

type CustomTypeFunc struct {
	Func  validator.CustomTypeFunc
	Types []interface{}
}

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.
	Write time.Duration `cfg:"write" default:"60s" validate:"min=1000000000"`
	// Idle timeout is the maximum amount of time to wait for the next request when keep-alives are enabled
	Idle time.Duration `cfg:"idle" default:"60s" validate:"min=1000000000"`
}

TimeoutSettings configures IO timeouts.

type ValidateAlias

type ValidateAlias struct {
	Alias string
	Tags  string
}

A ValidateAlias allows you to map one or more tags to a different name, making your validation rules easier to read.
