Functions ¶

func Check ¶

func Check(tree *parser.Tree, config *conf.Config) (reflect.Type, error)

Check calls Check on a disposable Checker.

func FieldIndex ¶ added in v1.15.8

func FieldIndex(c *Cache, env Nature, node ast.Node) (bool, []int, string)

func IsFastFunc ¶ added in v1.15.8

func IsFastFunc(fn reflect.Type, method bool) bool

func MethodIndex ¶ added in v1.15.8

func MethodIndex(c *Cache, env Nature, node ast.Node) (bool, int, string)

func ParseCheck ¶ added in v1.16.8

func ParseCheck(input string, config *conf.Config) (*parser.Tree, error)

ParseCheck parses input expression and checks its types. Also, it applies all provided patchers. In case of error, it returns error with a tree.

func TypedFuncIndex ¶ added in v1.15.8

func TypedFuncIndex(fn reflect.Type, method bool) (int, bool)

Types ¶

type Checker ¶ added in v1.17.7

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

func (*Checker) Check ¶ added in v1.17.7

func (v *Checker) Check(tree *parser.Tree, config *conf.Config) (reflect.Type, error)

Check checks types of the expression tree. It returns type of the expression and error if any. If config is nil, then default configuration will be used.

func (*Checker) PatchAndCheck ¶ added in v1.17.7

func (v *Checker) PatchAndCheck(tree *parser.Tree, config *conf.Config) (reflect.Type, error)

PatchAndCheck applies all patchers and checks the tree.
