Overview ¶
Package codec holds the types that [zip.Codecs] is proved against.
The proof it exists for is byte equality: for a type the REFLECTIVE encoder can write, the generated codec must write the same bytes and read back the same value. That is what lets a fleet roll a generated codec out one pod at a time — the pod on the old path and the pod on the new one are speaking one wire, not two — and it is the property a second derivation of the layout would silently break.
The fixtures cover every slot form the emitter has a branch for, plus the one the reflective encoder refuses outright: bytes_fixed[N], where there are no bytes to compare against because there are none at all.

Types ¶
type Count ¶
type Count uint64
Count is a defined scalar, which needs a conversion on the way in and out.
type Ided ¶
Ided is what the reflective encoder refuses: an id is [32]byte, and a fixed array has a layout the reflective codec deliberately does not carry.
func (*Ided) MarshalZAP ¶
MarshalZAP writes Ided from constant offsets.
func (*Ided) UnmarshalZAP ¶
UnmarshalZAP reads Ided out of the buffer that arrived.
type Leaf ¶
Leaf is a nested value and a list element.
func (*Leaf) MarshalZAP ¶
MarshalZAP writes Leaf from constant offsets.
func (*Leaf) UnmarshalZAP ¶
UnmarshalZAP reads Leaf out of the buffer that arrived.
type Loose ¶
Loose is Ided with no codec generated for it, which is what the reflective encoder is left holding when a type has not stated its wire.
type Trunk ¶
type Trunk struct {
B bool
I8 int8
I16 int16
I32 int32
I64 int64
U8 uint8
U16 uint16
U32 uint32
U64 uint64
F32 float32
F64 float64
C Count
Text string
Raw []byte
Leaf Leaf
PtrU *uint64
PtrS *string
PtrB *bool
PtrL *Leaf
Nums []uint32
Sigs []int32
Bigs []float64
Strs []string
Bufs [][]byte
Bits []bool
Kids []Leaf
Ptrs []*Leaf
}
Trunk carries one field of every form the emitter writes.
func (*Trunk) MarshalZAP ¶
MarshalZAP writes Trunk from constant offsets.
func (*Trunk) UnmarshalZAP ¶
UnmarshalZAP reads Trunk out of the buffer that arrived.
