Variables ¶
var ZKVMUTXOSchemaFields = struct { OutputIndex zapv1.Field[ZKVMUTXOSchema, uint32] Height zapv1.Field[ZKVMUTXOSchema, uint64] CommitmentOff zapv1.Field[ZKVMUTXOSchema, uint32] CommitmentLen zapv1.Field[ZKVMUTXOSchema, uint32] CiphertextOff zapv1.Field[ZKVMUTXOSchema, uint32] CiphertextLen zapv1.Field[ZKVMUTXOSchema, uint32] EphemeralPKOff zapv1.Field[ZKVMUTXOSchema, uint32] EphemeralPKLen zapv1.Field[ZKVMUTXOSchema, uint32] }{ OutputIndex: zapv1.At[ZKVMUTXOSchema, uint32](4), Height: zapv1.At[ZKVMUTXOSchema, uint64](8), CommitmentOff: zapv1.At[ZKVMUTXOSchema, uint32](48), CommitmentLen: zapv1.At[ZKVMUTXOSchema, uint32](52), CiphertextOff: zapv1.At[ZKVMUTXOSchema, uint32](56), CiphertextLen: zapv1.At[ZKVMUTXOSchema, uint32](60), EphemeralPKOff: zapv1.At[ZKVMUTXOSchema, uint32](64), EphemeralPKLen: zapv1.At[ZKVMUTXOSchema, uint32](68), }
ZKVMUTXOSchemaFields is the namespace of every scalar field accessor for ZKVMUTXO. Use with zapv1.Read / zapv1.Write for type-safe access. Byte-array fields are emitted as standalone functions, see below.
Functions ¶
func NewZKVMUTXO ¶
func NewZKVMUTXO(outputIndex uint32, height uint64, commitmentOff uint32, commitmentLen uint32, ciphertextOff uint32, ciphertextLen uint32, ephemeralPKOff uint32, ephemeralPKLen uint32, txID [32]byte) (zapv1.View[ZKVMUTXOSchema], []byte)
NewZKVMUTXO builds a fresh ZKVMUTXO in a ZAP buffer.
Hand-rolled fast path: inlines v1 primitives (zap.NewBuilder, [*Builder.StartObject], [*ObjectBuilder.Set*], [*Builder.Finish]) so the entire build expands at the call site. Result: 1 heap alloc (the buffer), zero overhead vs v1.
func WrapZKVMUTXO ¶
func WrapZKVMUTXO(b []byte) (zapv1.View[ZKVMUTXOSchema], error)
WrapZKVMUTXO parses a ZAP buffer into a typed [zapv1.View[ZKVMUTXO]]. Validates the wire frame and the kind discriminator at offset 0; returns *zapv1.SchemaError on kind mismatch.
Hand-rolled fast path: inlines zap.Parse (which is itself inlineable). Zero heap allocs on the happy path; matches v1 hand-rolled performance.
func ZKVMUTXOTxID ¶
func ZKVMUTXOTxID(v zapv1.View[ZKVMUTXOSchema]) [32]byte
ZKVMUTXOTxID reads the 32-byte inline TxID field of ZKVMUTXO.
Zero-copy on the read side (v1's Object.BytesFixedSlice returns a sub-slice of the underlying buffer); the returned [32]byte is a value copy so the caller's slot owns the bytes after the View's buffer is freed.
Types ¶
type ZKVMUTXOSchema ¶
type ZKVMUTXOSchema struct{}
ZKVMUTXOSchema is the v2 schema marker for ZKVMUTXO. Methods are constant- returning so concrete-typed [zapv1.Wrap[ZKVMUTXOSchema]] calls fold to literals at the call site.
func (ZKVMUTXOSchema) Kind ¶
func (ZKVMUTXOSchema) Kind() zapv1.KindByte
func (ZKVMUTXOSchema) Name ¶
func (ZKVMUTXOSchema) Name() string
func (ZKVMUTXOSchema) Size ¶
func (ZKVMUTXOSchema) Size() int
