Struct breez_sdk_liquid::bitcoin::blockdata::locktime::PackedLockTime

pub struct PackedLockTime(pub u32);

Packed lock time wraps a LockTime consensus value i.e., the raw u32 used by the network.

This struct may be preferred in performance-critical applications because it’s slightly smaller than LockTime and has a bit more performant (de)serialization. In particular, this may be relevant when the value is not processed, just passed around. Note however that the difference is super-small, so unless you do something extreme you shouldn’t worry about it.

This type implements a naive ordering based on the u32, this is not a semantically correct ordering for a lock time, hence LockTime does not implement Ord. This type is useful if you want to use a lock time as part of a struct and wish to derive Ord. For all other uses, consider using LockTime directly.

Examples

#[derive(Copy, Clone, PartialEq, Eq, PartialOrd, Ord, Debug, Hash)]
struct S {
    lock_time: PackedLockTime,
    amount: Amount,
}

let _ = S {
    lock_time: LockTime::from_consensus(741521).into(),
    amount: Amount::from_sat(10_000_000),
};

Implementations

impl PackedLockTime

pub const ZERO: PackedLockTime = _

If crate::Transaction::lock_time is set to zero it is ignored, in other words a transaction with nLocktime==0 is able to be included immediately in any block.

pub fn to_u32(self) -> u32

Returns the inner u32.
