Overview ¶
Package validation provides input validation utilities for DataFrame operations. This package implements a comprehensive validation framework with reusable validators for common validation scenarios like column existence, length consistency, type checking, and bounds validation.

Functions ¶
func ValidateColumns ¶
func ValidateColumns(df ColumnProvider, op string, columns ...string) error
ValidateColumns is a convenience function for column validation.
func ValidateIndex ¶
ValidateIndex is a convenience function for index validation.
func ValidateLength ¶
ValidateLength is a convenience function for length validation.
func ValidateNotEmpty ¶
func ValidateNotEmpty(df ColumnProvider, op string) error
ValidateNotEmpty is a convenience function for empty DataFrame validation.
Types ¶
type ColumnProvider ¶
type ColumnProvider interface {
HasColumn(name string) bool
Columns() []string
Len() int
Width() int
}
ColumnProvider interface for types that provide column information.
type ColumnValidator ¶
type ColumnValidator struct {
// contains filtered or unexported fields
}
ColumnValidator validates column existence and properties.
func NewColumnValidator ¶
func NewColumnValidator(df ColumnProvider, op string, columns ...string) *ColumnValidator
NewColumnValidator creates a validator for column operations.
func (*ColumnValidator) Validate ¶
func (v *ColumnValidator) Validate() error
Validate checks if all columns exist in the DataFrame.
type CompoundValidator ¶
type CompoundValidator struct {
// contains filtered or unexported fields
}
CompoundValidator combines multiple validators.
func NewCompoundValidator ¶
func NewCompoundValidator(validators ...Validator) *CompoundValidator
NewCompoundValidator creates a validator that checks multiple conditions.
func (*CompoundValidator) Validate ¶
func (v *CompoundValidator) Validate() error
Validate runs all validators and returns the first error encountered.
type EmptyDataFrameValidator ¶
type EmptyDataFrameValidator struct {
// contains filtered or unexported fields
}
EmptyDataFrameValidator validates operations on empty DataFrames.
func NewEmptyDataFrameValidator ¶
func NewEmptyDataFrameValidator(df ColumnProvider, op string) *EmptyDataFrameValidator
NewEmptyDataFrameValidator creates a validator for empty DataFrame checks.
func (*EmptyDataFrameValidator) Validate ¶
func (v *EmptyDataFrameValidator) Validate() error
Validate checks if DataFrame is empty when operation requires data.
type IndexValidator ¶
type IndexValidator struct {
// contains filtered or unexported fields
}
IndexValidator validates index bounds.
func NewIndexValidator ¶
func NewIndexValidator(index, maxIndex int, op string) *IndexValidator
NewIndexValidator creates a validator for index operations.
func (*IndexValidator) Validate ¶
func (v *IndexValidator) Validate() error
Validate checks if index is within bounds.
type LengthValidator ¶
type LengthValidator struct {
// contains filtered or unexported fields
}
LengthValidator validates array length consistency.
func NewLengthValidator ¶
func NewLengthValidator(expected, actual int, op, context string) *LengthValidator
NewLengthValidator creates a validator for length consistency.
func (*LengthValidator) Validate ¶
func (v *LengthValidator) Validate() error
Validate checks if lengths match.
type TypeValidator ¶
type TypeValidator struct {
// contains filtered or unexported fields
}
TypeValidator validates supported data types.
func NewTypeValidator ¶
func NewTypeValidator(value interface{}, op string, supportedTypes ...reflect.Type) *TypeValidator
NewTypeValidator creates a validator for type checking.
func (*TypeValidator) Validate ¶
func (v *TypeValidator) Validate() error
Validate checks if the value type is supported.
