ERRATUM: Sequence number clarified as incremented per “sFlow Instance” instead of “source_id”.

Fields

sFlow data source identifier

sampling_rate: u32

Sampling rate (1 in N packets)

sample_pool: u32

Total packets that could have been sampled

drops: u32

Number of dropped samples due to lack of resources

flow_records: Vec<FlowRecord>

Flow records describing the sampled packet

Trait Implementations

impl Clone for FlowSample

fn clone(&self) -> FlowSample

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FlowSample

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FlowSample

fn eq(&self, other: &FlowSample) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
