Functions

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.

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.

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

ZKVMUTXOSchema

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.
