VarLenPeek

sealed interface VarLenPeek<out T>

Result of peeking a self-delimiting value from a StreamProcessor prefix without consuming bytes. Modeled as a sum type (not a nullable) so the two states are explicit and exhaustive.

Types

Decoded

data class Decoded<out T>(val value: T, val byteCount: Int) : VarLenPeek<T>

The decoded value and the exact number of bytes it occupies on the wire.

NeedsMoreData

data object NeedsMoreData : VarLenPeek<Nothing>

Not enough bytes are buffered yet to determine the value or its length.
