Types ¶

type Def ¶

type Def struct {
	Kind  DefKind
	Name  TypeNameOccur
	Items []DefItem
}

Def represents either an enumeration, a primitive type, a struct, or a sum.

func Parse ¶

func Parse(filename string, src io.Reader) ([]Def, error)

Parse parses definitions from an io.Reader.

type DefItem ¶

type DefItem struct {
	Name    ItemNameOccur
	IsSlice bool
	Type    TypeNameOccur
	Tag     TagOccur
}

DefItem represents either an enumeration constant, a struct field, a sum alternative, or a reserved tag. Enumeration constants have a name. Struct fields have a name and a type. Sum alternatives have a type. Reserved tags have neither a name nor a type.

func (DefItem) IsReserved ¶

func (i DefItem) IsReserved() bool

IsReserved returns true if the item is a tag reservation.

type DefKind ¶

type DefKind int

DefKind determines the type of a definition.

const (
	EnumDef DefKind = iota
	PrimDef
	StructDef
	SumDef
)

DefKind values.

type ItemName ¶

type ItemName string

ItemName represents the name of an enumeration constant or a struct field.

func (ItemName) String ¶

func (in ItemName) String() string

type ItemNameOccur ¶

type ItemNameOccur struct {
	Name ItemName
	Pos  Pos
}

type Pos ¶

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

Pos represents a position in the input.

func (Pos) String ¶

func (pos Pos) String() string

type PosError ¶

type PosError struct {
	Pos Pos
	Err error
}

PosError wraps an error that occurred at a specific position in the input.

func (PosError) Error ¶

func (e PosError) Error() string

type Tag ¶

type Tag int32

Tag represents a protobuf tag number.

func (Tag) String ¶

func (t Tag) String() string

type TagOccur ¶

type TagOccur struct {
	Tag Tag
	Pos Pos
}

TagOccur represents an occurrence of a Tag in the input.

type TypeName ¶

type TypeName string
