Functions

LightClientBlockHeaderRequestBlockContentHash

func LightClientBlockHeaderRequestBlockContentHash(v zapv1.View[LCBlockHeaderReqSchema]) [32]byte

LightClientBlockHeaderRequestBlockContentHash reads the 32-byte inline BlockContentHash field of LightClientBlockHeaderRequest.

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.

NewLightClientBlockHeaderRequest

func NewLightClientBlockHeaderRequest(version uint8, chainID uint32, blockHeight uint64, certMinTier uint8, requestID uint32, blockContentHash [32]byte) (zapv1.View[LCBlockHeaderReqSchema], []byte)

NewLightClientBlockHeaderRequest builds a fresh LightClientBlockHeaderRequest 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.

WrapLightClientBlockHeaderRequest

func WrapLightClientBlockHeaderRequest(b []byte) (zapv1.View[LCBlockHeaderReqSchema], error)

WrapLightClientBlockHeaderRequest parses a ZAP buffer into a typed [zapv1.View[LightClientBlockHeaderRequest]]. 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.

Types

LCBlockHeaderReqSchema

LCBlockHeaderReqSchema is the v2 schema marker for LightClientBlockHeaderRequest. Methods are constant- returning so concrete-typed [zapv1.Wrap[LCBlockHeaderReqSchema]] calls fold to literals at the call site.
