Functions ¶
func CheckNilValues ¶
func CheckNilValues(params ...interface{}) error
CheckNilValues checks if any of the passed parameters are nil.
NOTE: Only parameters that have the possibility of being nil should be passed to this function. Passing a non-nil value of a type that cannot be nil (e.g., a string) will cause a panic.
Types ¶
type Validator ¶ added in v1.15.12
Validator is a function type that performs validation on a string value.
The function returns an error if the validation fails.
func NewE164PhoneValidator ¶
func NewE164PhoneValidator() Validator
NewE164Validator returns a validator that checks if a field is a string and is a valid E.164 phone number.
func NewNonNilPointerFieldElemIsUTCDateValidator ¶
func NewNonNilPointerFieldElemIsUTCDateValidator() Validator
NewNonNilPointerFieldElemIsUTCDateValidator returns a validator that checks if a field is a pointer, is not nil, and its underlying value is a valid UTC date.
func NewNonNilPointerValidator ¶
func NewNonNilPointerValidator() Validator
NewNonNilPointerValidator returns a validator that checks if a field is a pointer and is not nil.
func NewNonPointerFieldIntInsideRangeValidator ¶ added in v1.13.4
NewNonPointerFieldIntInsideRangeValidator returns a validator that checks if a field is an int and is inside a given range.
func NewNonZeroPointerElemValidator ¶
func NewNonZeroPointerElemValidator() Validator
NewNonNilPointerElemValidator returns a validator that checks if a field is a pointer, is not nil, and its underlying value is not zero.
func NewNonZeroValidator ¶
func NewNonZeroValidator() Validator
NewNonZeroValidator returns a validator that checks if a field is not a pointer and is not zero.
func NewPointerFieldIntInsideRangeValidator ¶ added in v1.13.4
NewPointerFieldIntInsideRangeValidator returns a validator that checks if a field is a pointer, is not nil, and its underlying value is an int inside a given range.
func NewPointerFieldIsValidBPC47Validator ¶ added in v1.14.6
func NewPointerFieldIsValidBPC47Validator() Validator
NewPointerFieldIsValidBPC47Validator returns a validator that checks if a field is a pointer, is not nil, and its underlying value is a valid BCP47 language tag.
type ValidatorRegistryInterface ¶
type ValidatorRegistryInterface interface {
AddValidator(string, Validator)
RunTags(interface{}, string) error
}
ValidatorRegistryInterface is an interface that defines the methods that a validatorRegistry must implement.
func NewValidatorRegistry ¶
func NewValidatorRegistry() ValidatorRegistryInterface
NewValidatorRegistry creates a new validatorRegistry and initializes its validators map.
It returns a ValidatorRegistryInterface.
