Function representable_samples 

pub(crate) fn representable_samples(
    first_sample_unix_ns: u64,
    sample_interval_ns: u64,
    count: usize,
) -> usize

Counts the leading samples of a scan whose timestamps fit in an i64.

These are exactly the indices for which sample_timestamp_ns succeeds.

Arguments

• first_sample_unix_ns - Time of the scan’s first sample, in Unix nanoseconds.
• sample_interval_ns - Time between samples, in nanoseconds.
• count - Number of samples in the scan.
