Struct elfo_core::tracing::TraceIdValidator

pub struct TraceIdValidator { /* private fields */ }

A TraceId validator.

By default, it checks the following properties:

• Cannot be zero.
• Must be 63-bit.
• Cannot have the same node no, because it’s sent outside the elfo system.

Optionally, it can also check the time difference, see TraceIdValidator::max_time_difference.

Implementations

impl TraceIdValidator

pub fn max_time_difference( &mut self, time_lag: impl Into<Option<Duration>> ) -> Self

Allowed time difference between now and timestamp in a raw trace id. Checks the absolute difference to handle both situations:

• Too old timestamp, possible incorrectly generated.
• Too new timestamp, something wrong with time synchronization.

pub fn validate(&self, raw_trace_id: u64) -> Result<TraceId, &'static str>

Validates a raw trace id transforms it into TraceId if valid.
