Struct linux_perf_data::PerfRecordIter

pub struct PerfRecordIter<R: Read> { /* private fields */ }

An iterator which incrementally reads and sorts the records from a perf.data file.

Implementations

impl<R: Read> PerfRecordIter<R>

pub fn next_record(
    &mut self,
    _perf_file: &mut PerfFile
) -> Result<Option<PerfFileRecord<'_>>, Error>

Iterates the records in this file. The records are emitted in the correct order, i.e. sorted by time.

next_record does some internal buffering so that the sort order can be guaranteed. This buffering takes advantage of FINISHED_ROUND records so that we don’t buffer more records than necessary.
