Functions

func DecodeOnlyString added in v0.65.0 

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

DecodeOnlyString is a mapstructure.HookFuncType that decodes a string value as an OnlyString, but fails on all other values. It is useful to force parsing of a field that can contain just digits as a string, when the leading digit might be 0.

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 type, 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.

func MapLoggingFields added in v0.50.0 

func MapLoggingFields(value interface{}) logging.Fields

MapLoggingFields returns all logging.Fields formatted based on our configuration keys 'dot.name.key' with associated values. Supports squash, and secret to skip printing out secrets.

func Unmarshal added in v0.90.0 

func Unmarshal(c *Config) error

func ValidateMissingRequiredKeys added in v0.48.0 

func ValidateMissingRequiredKeys(value interface{}, tag, squashValue string) []string

ValidateMissingRequiredKeys returns all keys of value in GetStructKeys format that have an additional required tag set but are unset.

Config - Output struct of configuration, used to validate. If you read a key using a viper accessor rather than accessing a field of this struct, that key will *not* be validated. So don't do that.
