Function sample_timestamp_ns 

pub(crate) fn sample_timestamp_ns(
    first_sample_unix_ns: u64,
    sample_interval_ns: u64,
    index: usize,
) -> Result<i64, String>

Computes the Unix timestamp for a sample index within a FlatBuffer scan.

Arguments

• first_sample_unix_ns - Time of the scan’s first sample, in Unix nanoseconds.
• sample_interval_ns - Time between samples, in nanoseconds.
• index - Zero-based sample index within the scan.

Returns

first_sample_unix_ns + sample_interval_ns * index, in Unix nanoseconds.

Errors

Returns an error if the result does not fit in an i64.

Examples

sample_timestamp_ns(1_000, 500_000, 3) == Ok(1_501_000)
