Functions

func DecodeStrings added in v0.40.0 

func DecodeStrings(fromValue reflect.Value, toValue reflect.Value) (interface{}, error)

decodeStrings is a mapstructure.HookFuncType that decodes a single string value or a slice of strings into Strings.

func GetStructKeys added in v0.40.0 

func GetStructKeys(typ reflect.Type, tag, squashValue string) []string

GetStructKeys returns all keys in a nested struct, taking the name from the tag name or the field name. It handles an additional suffix squashValue like mapstructure does: if present on an embedded struct, name components for that embedded struct should not be included. It does not handle maps, does chase pointers, but does not check for loops in nesting.

type Config struct {
	// contains filtered or unexported fields
}
