Functions ¶

func ConvertLiteralCheckOverflow ¶

func ConvertLiteralCheckOverflow(src interface{}, to xr.Type) interface{}

ConvertLiteralCheckOverflow converts a literal to type t and returns the converted value. panics if the conversion overflows the given type

func Marshal ¶

func Marshal(kind Kind, val constant.Value) string

Types ¶

type Kind ¶

type Kind r.Kind

untyped kind. matches reflect.Kind except for rune literals, where Kind == reflect.Int32

func GoUntypedToKind ¶

func GoUntypedToKind(gkind types.BasicKind) Kind

func MakeKind ¶

func MakeKind(ckind constant.Kind) Kind

func Unmarshal ¶

func Unmarshal(marshalled string) (Kind, constant.Value)

func (Kind) Category ¶

func (k Kind) Category() r.Kind

func (Kind) Reflect ¶

func (k Kind) Reflect() r.Kind

func (Kind) String ¶

func (k Kind) String() string

type Lit ¶

type Lit struct {
	Kind Kind // untyped constant's default type
	Val  constant.Value
	// contains filtered or unexported fields
}

Lit represents an untyped literal value, i.e. an untyped constant

func MakeLit ¶

func MakeLit(kind Kind, val constant.Value, basicTypes *[]xr.Type) Lit

func (*Lit) BigFloat ¶

func (untyp *Lit) BigFloat() *big.Float

func (*Lit) BigInt ¶

func (untyp *Lit) BigInt() *big.Int

func (*Lit) BigRat ¶

func (untyp *Lit) BigRat() *big.Rat

func (*Lit) Convert ¶

func (untyp *Lit) Convert(t xr.Type) interface{}

Convert checks that an untyped.Lit can be converted exactly to the given type. performs actual untyped -> typed conversion and subsequent overflow checks. returns the constant.Value converted to given type

func (*Lit) DefaultType ¶

func (untyp *Lit) DefaultType() xr.Type

DefaultType returns the default type of an untyped constant.

func (*Lit) EqualInt64 ¶

func (untyp *Lit) EqualInt64(i int64) bool

func (*Lit) Float64 ¶

func (untyp *Lit) Float64() (float64, bool)

func (*Lit) Int64 ¶

func (untyp *Lit) Int64() (int64, bool)

func (Lit) String ¶

func (untyp Lit) String() string

pretty-print untyped constants

func (*Lit) Uint64 ¶

func (untyp *Lit) Uint64() (uint64, bool)

type Val ¶

type Val struct {
	Kind Kind // default type
	Val  constant.Value
}

untyped value

func UnmarshalVal ¶

func UnmarshalVal(marshalled string) *Val

func (*Val) BigInt ¶

func (lit *Val) BigInt() (*big.Int, error)

func (*Val) BigRat ¶

func (lit *Val) BigRat() (*big.Rat, error)

func (*Val) Marshal ¶

func (val *Val) Marshal() string
