Struct linux_perf_event_reader::MmapRecord

pub struct MmapRecord<'a> {
    pub pid: i32,
    pub tid: i32,
    pub address: u64,
    pub length: u64,

}

These aren’t emitted by the kernel any more - the kernel uses MMAP2 events these days. However, perf record still emits synthetic MMAP events (not MMAP2!) for the kernel image. So if you want to symbolicate kernel addresses you still need to process these. The kernel image MMAP events have pid -1.

Fields

pid: i32

tid: i32

address: u64

Implementations

impl<'a> MmapRecord<'a>

pub fn parse<T: ByteOrder>(data: RawData<'a>, misc: u16) -> Result<Self, Error>

Trait Implementations

impl<'a> Clone for MmapRecord<'a>

fn clone(&self) -> MmapRecord<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for MmapRecord<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for MmapRecord<'a>

fn eq(&self, other: &MmapRecord<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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