Structure representing the extra type properties of a fragment.

Fields

pk_cost: usize

The number of bytes needed to encode its scriptpubkey

has_free_verify: bool

Whether this fragment can be verify-wrapped for free

ops_count_static: usize

The worst case static(unexecuted) ops-count for this Miniscript fragment.

ops_count_sat: Option<usize>

The worst case ops-count for satisfying this Miniscript fragment.

ops_count_nsat: Option<usize>

The worst case ops-count for dissatisfying this Miniscript fragment.

stack_elem_count_sat: Option<usize>

The worst case number of stack elements for satisfying this Miniscript fragment.

stack_elem_count_dissat: Option<usize>

The worst case number of stack elements for dissatisfying this Miniscript fragment.

max_sat_size: Option<(usize, usize)>

Maximum size, in bytes, of a satisfying witness. First elements is the cost for the witness stack, the second one is the cost for scriptSig. All signatures are assumed to be 73 bytes in size, including the length prefix (segwit) or push opcode (pre-segwit) and sighash postfix.

max_dissat_size: Option<(usize, usize)>

Maximum dissatisfaction cost, in bytes, of a Miniscript fragment. First elements is the cost for the witness stack, the second one is the cost for scriptSig.

timelock_info: TimeLockInfo

The timelock info about heightlocks and timelocks
