Types

type Cast

type Cast interface {
	File() (*ast.File, *token.FileSet)
}

Cast describes a generic AST template.

type Serialized

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

Serialized is byte buffer baked AST template.

func FromAST

func FromAST(filename string, file *ast.File) *Serialized

FromAST creates a new serialized AST template from given AST. If the AST template is invalid, this function can panic.

func FromRe

func FromRe(filename string, src io.Reader) (*Serialized, error)

FromRe creates a new serialized AST template from given byte source. Returns any error encountered.

func MustFromRe

func MustFromRe(filename string, src io.Reader) *Serialized

MustFromRe creates a serialized AST from given byte source. Panics on error

func (*Serialized) AST

func (cast *Serialized) AST() (*ast.File, *token.FileSet)

AST return the internal AST template.

func (*Serialized) Name

func (cast *Serialized) Name() string

Name returns the filename of the serialized template.

func (*Serialized) Reader

func (cast *Serialized) Reader() *bytes.Reader

Reader returns the template as a byte reader.
