Struct DecisionId 

pub struct DecisionId(/* private fields */);

128-bit identifier linking a runtime decision to its EvidenceLedger entry.

Structurally identical to TraceId but semantically distinct.

Implementations

impl DecisionId

pub const fn from_raw(raw: u128) -> Self

Create from raw 128-bit value.

pub const fn from_parts(ts_ms: u64, random: u128) -> Self

Create from millisecond timestamp and random bits.

ts_ms is saturated to the 48-bit field (matching TraceId::from_parts) so an out-of-range value — e.g. microseconds or nanoseconds passed by a unit-error — never silently corrupts the “high 48 = ts, low 80 = random” layout. Without saturation, (ts_ms as u128) << 80 shifts the top bits of an out-of-range ts_ms off the 128-bit word, so timestamp_ms would return a truncated value. Use Self::try_from_parts for a strict, error-returning surface. (br-asupersync-rxe2sg)

pub const fn try_from_parts(ts_ms: u64, random: u128) -> Result<Self, u64>

Strict variant of Self::from_parts (br-asupersync-rxe2sg).

Returns Err(ts_ms) when the millisecond timestamp does not fit in the 48-bit field, mirroring TraceId::try_from_parts.

Errors

Returns Err(ts_ms) if ts_ms >= 2^48.

pub const fn timestamp_ms(self) -> u64

Extract the millisecond timestamp.

pub const fn as_u128(self) -> u128

Return the raw 128-bit value.

pub const fn to_bytes(self) -> [u8; 16]

Return the bytes in big-endian order.

pub const fn from_bytes(bytes: [u8; 16]) -> Self

Construct from big-endian bytes.
