Struct redbpf::PerCpuValues

pub struct PerCpuValues<T: Clone>(_);

A structure representing values of per-cpu map structures such as PerCpuArray

It is a kind of newtype of Box<[T]>. The length of the slice is always the same with cpus::get_possible_num. It also implements Deref and DerefMut so it can be used as a normal array.

Example

use redbpf::PerCpuValues;
let mut values = PerCpuValues::<u64>::new(0);
values[0] = 1;

Implementations

impl<T: Clone> PerCpuValues<T>

pub fn new(default_value: T) -> Self

Create a PerCpuValues<T> instance

The created instance contains the fixed number of elements filled with default_value
