Pointer

The names of the product elements

The name of the type

Parse a pointer that takes the whole byte array, as a node reads one in a new transaction (protocol version 9 and later): bytes after the pointer fail.

Parse a pointer that takes the whole byte array, as a node reads one at protocolVersion (see parseFrom).

From version 7 bytes after the pointer fail, as the ledger's ensureBufIsConsumed; before it they are dropped, as a node drops them.

Parse pointer from bytes starting at given index, as a node reads one in a new transaction (protocol version 9 and later).

A slot past MaxSlot, or an index past MaxIndex, fails, as does a number that takes more bytes than its width needs. This is the ledger's decodePtr.

Parse pointer from bytes starting at given index, as a node reads one at protocolVersion.

From version 9 a pointer that does not fit fails, as without a protocol version. Before it, each number may take any number of bytes and keeps its low 64 bits, and a slot past MaxSlot, or an index past MaxIndex, makes the whole pointer Pointer(Slot(0), 0, 0). This is the ledger's decodePtrLenient and mkPtrNormalized, and so what a node holds for such an address in its UTxO set.

The largest transaction or certificate index a pointer holds: the ledger's are 16 bits.

The largest slot a pointer holds: the ledger's slot is 32 bits.
