Struct miniscript::miniscript::types::extra_props::ExtData

pub struct ExtData {
    pub pk_cost: usize,
    pub has_free_verify: bool,
    pub ops_count_static: usize,
    pub ops_count_sat: Option<usize>,
    pub ops_count_nsat: Option<usize>,
    pub timelock_info: TimeLockInfo,
}

Structure representing the extra type properties of a fragment which are relevant to legacy(pre-segwit) safety and fee estimation. If a fragment is used in pre-segwit transactions it will only be malleable but still is correct and sound.

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.

timelock_info: TimeLockInfo

The timelock info about heightlocks and timelocks
