This crate lets you parse Linux perf events and associated structures.
```rust use linuxperfeventreader::{Endianness, PerfEventAttr, RawData, RecordType}; use linuxperfeventreader::records::{CommOrExecRecord, EventRecord, RawEventRecord, RecordParseInfo};
// Read the perfeventattr data. let attrdata = vec![ 0, 0, 0, 0, 128, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 229, 3, 0, 0, 0, 0, 0, 0, 47, 177, 0, 0, 0, 0, 0, 0, 4, 0, 0, 0, 0, 0, 0, 0, 3, 183, 215, 97, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 255, 15, 255, 0, 0, 0, 0, 0, 0, 128, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 104, 0, 0, 0, 0, 0, 0, 0, 128, 0, 0, 0, 0, 0, 0, 0, ]; let attr = PerfEventAttr::parse::<_, byteorder::LittleEndian>(&attrdata[..], None).unwrap(); let parse_info = RecordParseInfo::new(&attr, Endianness::LittleEndian);
