Struct TimeLockParams 

pub struct TimeLockParams {
    pub time_precision: u8,
    pub time_format: u8,
    pub cadence_variant: u8,
    pub salts: TimeLockSalts,
    pub kdf_params: KdfParams,
}

Compact, self-contained encoding of all encryption-time settings — suitable for plaintext storage within a ciphertext header.

Produced by pack and supplied to timelock or timelock_async as params: Some(header) on the decryption side. Only the cadence variant discriminant is recorded; the actual calendar values (weekday, day-of-month, month) are not stored and are instead read from the live system clock during decryption.

Field	Encoding / Notes
time_precision	0=Hour · 1=Quarter · 2=Minute
time_format	0=12 hr (Hour12) · 1=24 hr (Hour24)
cadence_variant	0=None · 1=DayOfWeek · 2=DayOfMonth
	3=MonthOfYear · 4=DayOfWeekInMonth
	5=DayOfMonthInMonth · 6=DayOfWeekAndDayOfMonth
salts	Three 32-byte salts (not secret; prevent precomputation)
kdf_params	Argon2id + scrypt work factors

Fields

time_precision: u8

0 = TimePrecision::Hour, 1 = TimePrecision::Quarter, 2 = TimePrecision::Minute.

time_format: u8

0 = TimeFormat::Hour12 (12-hour clock), 1 = TimeFormat::Hour24 (24-hour clock).

cadence_variant: u8

TimeLockCadence variant discriminant (0–6). The actual calendar values for that variant (which weekday, which month, etc.) are not stored here — the decryption path reads them from the clock.

salts: TimeLockSalts

Three KDF salts generated at encryption time.

Salts are not secret; storing them in the header is standard practice and prevents precomputation attacks.

kdf_params: KdfParams

The KDF work-factor parameters used at encryption time.

Stored so the decryption side uses identical memory and iteration costs.

Trait Implementations
