Types ¶
type FieldError ¶
FieldError represents a validation error for a specific field.
type ValidationError ¶
type ValidationError struct {
Errors []FieldError `json:"errors"`
}
ValidationError represents a collection of validation errors.
func (*ValidationError) Error ¶
func (e *ValidationError) Error() string
Error implements the error interface.
func (*ValidationError) HasErrors ¶
func (e *ValidationError) HasErrors() bool
HasErrors returns true if there are validation errors.
type Validator ¶
type Validator struct {
// contains filtered or unexported fields
}
Validator collects validation errors.
func (*Validator) MaxLength ¶
MaxLength validates that a string doesn't exceed max length (in runes).
func (*Validator) NoControlChars ¶
NoControlChars validates that a string doesn't contain control characters (except common whitespace).
func (*Validator) NoDangerousChars ¶
NoDangerousChars validates that a string doesn't contain potentially dangerous characters. This is a basic sanitization check for fields that shouldn't contain special chars.
func (*Validator) NonNegative ¶
NonNegative validates that an int is non-negative (>= 0).
func (*Validator) NonNegativeFloat ¶
NonNegativeFloat validates that a float64 is non-negative (>= 0).
func (*Validator) PositiveFloat ¶
PositiveFloat validates that a float64 is positive (> 0).
func (*Validator) RangeFloat ¶
RangeFloat validates that a float64 is within range (inclusive).
func (*Validator) RequiredInt ¶
RequiredInt validates that an int field is not zero.
func (*Validator) RequiredInt64 ¶
RequiredInt64 validates that an int64 field is not zero.
