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
	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 {
	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.
