Overview ¶
package zebra specifies the ZebraPack serialization format. To bootstrap, the ZebraPack schema is itself stored in msgpack2 (with optional JSON) format with embedded strings for field names.

Types ¶
type Field ¶
type Field struct {
// Zid is the zebrapack id
Zid int64
// the name of the field in the Go schema/source file.
FieldGoName string
// optional wire-name designated by a
// `msg:"tagname"` tag on the struct field.
FieldTagName string
// human readable/Go type description
FieldTypeStr string `msg:",omitempty"`
// the broad category of this type. empty if Skip is true
FieldCategory Zkind `msg:",omitempty"`
// avail if FieldCategory == BaseElemCat
FieldPrimitive Zkind `msg:",omitempty"`
// the machine-parse-able type tree
FieldFullType *Ztype `msg:",omitempty"`
// if OmitEmpty then we don't serialize
// the field if it has its zero-value.
OmitEmpty bool `msg:",omitempty"`
// Skip means either type struct{} or
// other unserializable type;
// or marked as `msg:"-"`. In any case,
// if Skip is true: do not serialize
// this field when writing, and ignore it
// when reading.
Skip bool `msg:",omitempty"`
// Deprecated means tagged with `deprecated:"true"`.
// Compilers/libraries should discourage and warn
// users away from writing to such fields, while
// not making it impossible to either read or write
// the field.
Deprecated bool `msg:",omitempty"`
}
Field represents fields within a struct.
func (*Field) DecodeMsg ¶
DecodeMsg implements msgp.Decodable We treat empty fields as if we read a Nil from the wire.
func (*Field) MarshalMsg ¶
MarshalMsg implements msgp.Marshaler
func (*Field) Msgsize ¶
Msgsize returns an upper bound estimate of the number of bytes occupied by the serialized message
func (*Field) UnmarshalMsg ¶
UnmarshalMsg implements msgp.Unmarshaler
func (*Field) UnmarshalMsgWithCfg ¶
type Schema ¶
type Schema struct {
SourcePath string
SourcePackage string
ZebraSchemaId int64
Structs []Struct
Imports []string
}
Schema is the top level container
func (*Schema) DecodeMsg ¶
DecodeMsg implements msgp.Decodable We treat empty fields as if we read a Nil from the wire.
func (*Schema) MarshalMsg ¶
MarshalMsg implements msgp.Marshaler
func (*Schema) Msgsize ¶
Msgsize returns an upper bound estimate of the number of bytes occupied by the serialized message
func (*Schema) UnmarshalMsg ¶
UnmarshalMsg implements msgp.Unmarshaler
func (*Schema) UnmarshalMsgWithCfg ¶
type Struct ¶
Struct represents a single message or struct.
func (*Struct) DecodeMsg ¶
DecodeMsg implements msgp.Decodable We treat empty fields as if we read a Nil from the wire.
func (*Struct) MarshalMsg ¶
MarshalMsg implements msgp.Marshaler
func (*Struct) Msgsize ¶
Msgsize returns an upper bound estimate of the number of bytes occupied by the serialized message
func (*Struct) UnmarshalMsg ¶
UnmarshalMsg implements msgp.Unmarshaler
func (*Struct) UnmarshalMsgWithCfg ¶
type Zkind ¶
type Zkind uint64
Zkind describes the detailed type of the field implentation note: must correspond to gen/Primitive Since it also stores the fixed size of a array type, it needs to be large. When serialized as msgpack2, it will be compressed.
const ( // primitives // implementation note: must correspond to gen/Primitive. Invalid Zkind = 0 Bytes Zkind = 1 // []byte String Zkind = 2 Float32 Zkind = 3 Float64 Zkind = 4 Complex64 Zkind = 5 Complex128 Zkind = 6 Uint Zkind = 7 // 32 or 64 bit; as in Go, matches native word Uint8 Zkind = 8 Uint16 Zkind = 9 Uint32 Zkind = 10 Uint64 Zkind = 11 Byte Zkind = 12 Int Zkind = 13 // as in Go, matches native word size. Int8 Zkind = 14 Int16 Zkind = 15 Int32 Zkind = 16 Int64 Zkind = 17 Bool Zkind = 18 Intf Zkind = 19 // interface{} Time Zkind = 20 // time.Time Ext Zkind = 21 // extension // IDENT means an unrecognized identifier; // it typically means a named struct type. IDENT Zkind = 22 // compound types // implementation note: should correspond to gen/Elem. BaseElemCat Zkind = 23 MapCat Zkind = 24 StructCat Zkind = 25 SliceCat Zkind = 26 ArrayCat Zkind = 27 PointerCat Zkind = 28 )
func ZkindFromString ¶
func (*Zkind) DecodeMsg ¶
DecodeMsg implements msgp.Decodable We treat empty fields as if we read a Nil from the wire.
func (Zkind) MarshalMsg ¶
MarshalMsg implements msgp.Marshaler
func (Zkind) Msgsize ¶
Msgsize returns an upper bound estimate of the number of bytes occupied by the serialized message
func (*Zkind) UnmarshalMsg ¶
UnmarshalMsg implements msgp.Unmarshaler
func (*Zkind) UnmarshalMsgWithCfg ¶
type Ztype ¶
type Ztype struct {
// Kind gives the exact type for primitives,
// and the category for compound types.
Kind Zkind
// Str holds the struct name when Kind == 22 (IDENT).
// Otherwise it typically reflects Kind directly
// which is useful for human readability.
Str string `msg:",omitempty"`
// Domain holds the key type for maps. For
// pointers and slices it holds the element type.
// For arrays, it holds the fixed size.
// Domain is null when Kind is a primitive
Domain *Ztype `msg:",omitempty"`
// Range holds the value type for maps.
// For arrays (always a fixed size), Range holds
// the element type. Otherwise Range is
// typically null.
Range *Ztype `msg:",omitempty"`
}
Ztype describes any type, be it a BaseElem, Map, Struct, Slice, Array, or Pointer.
func (*Ztype) DecodeMsg ¶
DecodeMsg implements msgp.Decodable We treat empty fields as if we read a Nil from the wire.
func (*Ztype) MarshalMsg ¶
MarshalMsg implements msgp.Marshaler
func (*Ztype) Msgsize ¶
Msgsize returns an upper bound estimate of the number of bytes occupied by the serialized message
