Functions

func Register 

func Register(importPath string, p *Package)

func ToBuiltin 

func ToBuiltin(b *Builtin) *adt.Builtin

ToBuiltin converts a Builtin into an adt.Builtin.

Types

type Bottomer 

type Bottomer interface {
	error
	Bottom() *adt.Bottom
}

type Builtin 

type Builtin struct {
	Name        string
	Pkg         adt.Feature
	Params      []Param
	Result      adt.Kind
	NonConcrete bool
	Func        func(c *CallCtxt)
	Const       string
}

A Builtin is a Builtin function or constant.

A function may return and a constant may be any of the following types: 

error (translates to bottom)
nil   (translates to null)
bool
int*
uint*
float64
string
*big.Float
*big.Int

For any of the above, including interface{} and these types recursively:
[]T
map[string]T

type CallCtxt 

type CallCtxt struct {
	*adt.CallContext

	Err interface{}
	Ret interface{}
	// contains filtered or unexported fields
}

CallCtxt is passed to builtin implementations that need to use a cue.Value. This is an internal type. Its interface may change.

func (*CallCtxt) BigFloat 

func (c *CallCtxt) BigFloat(i int) *big.Float

func (*CallCtxt) BigInt 

func (c *CallCtxt) BigInt(i int) *big.Int

func (*CallCtxt) Bool 

func (c *CallCtxt) Bool(i int) bool

func (*CallCtxt) Byte 

func (c *CallCtxt) Byte(i int) uint8

func (*CallCtxt) Bytes 

func (c *CallCtxt) Bytes(i int) []byte

func (*CallCtxt) CueList 

func (c *CallCtxt) CueList(i int) List

func (*CallCtxt) Decimal 

func (c *CallCtxt) Decimal(i int) *apd.Decimal

func (*CallCtxt) DecimalList 

func (c *CallCtxt) DecimalList(i int) (a []*apd.Decimal)

func (*CallCtxt) Do 

func (c *CallCtxt) Do() bool

Do returns whether the call should be done.

func (*CallCtxt) Float64 

func (c *CallCtxt) Float64(i int) float64

func (*CallCtxt) Int 

func (c *CallCtxt) Int(i int) int

func (*CallCtxt) Int16 

func (c *CallCtxt) Int16(i int) int16

func (*CallCtxt) Int32 

func (c *CallCtxt) Int32(i int) int32

func (*CallCtxt) Int64 

func (c *CallCtxt) Int64(i int) int64

func (*CallCtxt) Int8 

func (c *CallCtxt) Int8(i int) int8

func (*CallCtxt) Iter 

func (c *CallCtxt) Iter(i int) (a cue.Iterator)

func (*CallCtxt) List 

func (c *CallCtxt) List(i int) (a []cue.Value)

func (*CallCtxt) Name 

func (c *CallCtxt) Name() string

func (*CallCtxt) Pos 

func (c *CallCtxt) Pos() token.Pos

func (*CallCtxt) Reader 

func (c *CallCtxt) Reader(i int) io.Reader

func (*CallCtxt) Rune 

func (c *CallCtxt) Rune(i int) rune

func (*CallCtxt) Schema added in v0.11.0 

func (c *CallCtxt) Schema(i int) Schema

Schema returns the ith argument as is, without converting it to a cue.Value.

TODO: Schema should use CallContext.Expr to capture cycle information. However, this only makes sense if functions also use the same OpContext for further evaluation. We should enforce as we port the old calls.

func (*CallCtxt) String 

func (c *CallCtxt) String(i int) string

func (*CallCtxt) StringList 

func (c *CallCtxt) StringList(i int) (a []string)

func (*CallCtxt) Struct 

func (c *CallCtxt) Struct(i int) Struct

func (*CallCtxt) Uint 

func (c *CallCtxt) Uint(i int) uint

func (*CallCtxt) Uint16 

func (c *CallCtxt) Uint16(i int) uint16

func (*CallCtxt) Uint32 

func (c *CallCtxt) Uint32(i int) uint32

func (*CallCtxt) Uint64 

func (c *CallCtxt) Uint64(i int) uint64

func (*CallCtxt) Uint8 

func (c *CallCtxt) Uint8(i int) uint8

func (*CallCtxt) Value 

func (c *CallCtxt) Value(i int) cue.Value

Value returns a finalized cue.Value for the ith argument.

type List 

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

List represents a CUE list, which can be open or closed.

func (*List) Elems 

func (l *List) Elems() []*adt.Vertex

Elems returns the elements of a list.

func (*List) IsOpen 

func (l *List) IsOpen() bool

IsOpen reports whether a list is open ended.

type Package 

type Package struct {
	Native []*Builtin
	CUE    string
}

func (*Package) MustCompile 

func (p *Package) MustCompile(ctx *adt.OpContext, importPath string) *adt.Vertex

type Param 

type Param struct {
	Kind  adt.Kind
	Value adt.Value // input constraint (may be nil)
}

type Schema added in v0.11.0 

type Schema = cue.Value

A Schema represents an arbitrary cue.Value that can hold non-concrete values. By default function arguments are checked to be concrete.

type Struct 

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

Struct represents a CUE struct, which can be open or closed.

func (*Struct) Arcs 

func (s *Struct) Arcs() []*adt.Vertex

Arcs returns all arcs of s.

func (*Struct) IsOpen 

func (s *Struct) IsOpen() bool

IsOpen reports whether s is open or has pattern constraints.

func (s *Struct) Len() int

Len reports the number of regular string fields of s.

func (s Struct) NumConstraintFields() (count int)

NumConstraintFields reports the number of explicit optional and required fields, excluding pattern constraints.

type ValidationError 

type ValidationError struct {
	B *adt.Bottom
}

A ValidationError indicates an error that is only valid if a builtin is used as a validator.

func (ValidationError) Error
