Struct rxdp::PerfMap[−][src]

pub struct PerfMap<T> { /* fields omitted */ }

Used for working with a perf eBPF map.

Implementations

impl<T: 'static + Copy + Send> PerfMap<T>[src]

pub fn new(xdp: &XDPLoadedObject, map_name: &str) -> XDPResult<PerfMap<T>>[src]

Get access to the eBPF map map_name.

Errors

Returns an error in the following cases:

  • The requested key size doesn’t match the key size defined in the ELF file.
  • The map_type is not MapType::PerfEventArray.

pub fn start_polling(&mut self, time_ms: i32) -> Receiver<PerfEvent<T>>[src]

Start polling the underlying eBPF map for events, waiting up to time_ms milliseconds for an event. Returns the receiver side of an unbounded channel, which will receive all events.
