Types

type Engine

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

Engine is an OPA engine

func New

func New(policyFile string, module []byte) *Engine

New reads a policy file and returns a new engine

func (*Engine) Compile

func (e *Engine) Compile(ctx context.Context, query string, input interface{}, unknowns ...string) (Result, error)

Compile compiles the query

type Expr

type Expr struct {
	// Operator is the operator
	Operator Operator
	Left     *Operand
	Right    *Operand
}

Expr is an expression

type Operand

type Operand struct {
	// T is the operand type
	T OperandType
	// V is the operand value
	V interface{}
}

Val is an expression value

type OperandType

type OperandType int

OperandType is a value type

const (
	OperandTypeConstant OperandType = iota + 1
	OperandTypeIndexField
)

List of operand types

func (OperandType) String

func (vt OperandType) String() string

type Operator

type Operator int

const (
	OperatorEq Operator = iota + 1
)

func (Operator) String

func (op Operator) String() string

type Result

type Result struct {
	Defined bool
	Exprs   []*Expr
}

Result is a compilation result
