Overview ¶
Package flatbuffers implements a thin passthrough codec for already-encoded FlatBuffer payloads. The universal Codec contract speaks `any`, but FlatBuffers is a schema-driven format whose typed access lives in caller code (generated by `flatc`). This package therefore registers a codec that round-trips raw FlatBuffer bytes — Marshal hands back the buffer the caller already has; Unmarshal publishes the buffer to the caller's target without parsing it. Real schema-typed reads stay in the caller's generated accessors.
The codec uses no third-party dependency. The only validation is the 4-byte root-offset header required by the FlatBuffers wire format.
Package flatbuffers — small adapter interfaces that let strongly-typed FlatBuffers wrappers participate in the universal codec contract without reaching into schema-generated structs from this package.

Constants ¶
const PromotionMagic uint32 = 0x80000001
PromotionMagic is the synthetic little-endian uint32 header stamped by the facade promotion path in pkg/v1/data/codec/promote.go when it wraps a non-FlatBuffer value in flatbuffers-shaped bytes. 0x80000001 is a deliberately invalid root offset (a real root offset points INTO the buffer, never past it AND never the high bit set), so a flatc- generated reader fails predictably on these bytes — only the SDK itself recognises and unwraps them.
Exported so promote.go can stamp the same value without a duplicated magic-number constant.
Variables ¶
var ( //: register the singleton and expose it as a typed package var. Codec codec.Codec = codec.Register(&flatbuffersCodec{}) )
Package-level state: the codec singleton plus the hoisted MIME / extension tables.
Functions ¶
Types ¶
type BytesAcceptor ¶
type BytesAcceptor interface {
SetBytes(data []byte)
}
BytesAcceptor is the optional sink interface an Unmarshal target may satisfy to receive the decoded FlatBuffer payload. The codec passes the caller's data slice by reference; implementations that need ownership MUST copy the slice themselves.
type BytesProvider ¶
type BytesProvider interface {
Bytes() []byte
}
BytesProvider is the optional source interface a Marshal argument may satisfy to hand the codec its already-encoded FlatBuffer payload. The returned slice MUST remain valid for the lifetime of the codec call; the codec performs no copy and treats the buffer as read-only.
`Provider`/`Acceptor` suffixes are registered as legitimate adapter-role vocabulary in `/workspace/.ktn-linter.yaml` (per kodflow/ktn-linter#337), so `KTN-INTERFACE-ERNAME` does not fire here.
