Struct TimestampEncoder 

pub struct TimestampEncoder { /* private fields */ }

Converts absolute timestamps into the serialized form of the trace stream. See “Timestamps” in the docs of TraceRow.

The state can be copied, so that it can be restored when a row is removed again.

Implementations

impl TimestampEncoder

pub fn encode(&mut self, ts: u64) -> (Option<u64>, DeltaEncodedTimestamp)

Returns the value to serialize for the absolute timestamp ts, and, if needed, the timestamp of a TraceRow::TimestampBase row that has to be written before it.

A base is needed for the first timestamp, and when the difference to the previous timestamp doesn’t fit into an i64.

pub fn encode_row<'a>( &mut self, row: TraceRow<'a, u64>, ) -> (Option<TraceRow<'static>>, TraceRow<'a>)

Converts row into its serialized form. Also returns the TraceRow::TimestampBase row that has to be written before it, if needed.
