Sequence ToU64



↳ var truncate: bool = true
↳ var or_default: u64 = 0


value: Stream<Vec<u128>>


↦ value: Stream<Vec<u64>>

Convert stream of Vec<u128> into Vec<u64> one.

Vec<u128> gets converted into Vec<u64>, and the resulting vectors are send through stream in continuity.

As this conversion might be lossy (every possible u128 value cannot fit into u64), truncate allows value to be truncated to fit into a u64, and or_default set the value that is assigned when a u128 is out of range for u64 and truncation not allowed.

Truncation happens on the binary level, thus: 10010110 (150 if unsigned, -106 if signed) → 0110 (6).
