Struct bpf_rs::BpfHelper

pub struct BpfHelper(pub u32);

eBPF helper function wrapper. See bpf-helpers(7)

Tuple field BpfHelper::0 represents the unique id reserved by the kernel to represent the helper function. This unique id works almost as a counter with a max value: __BPF_FUNC_MAX_ID. This max limit changes between kernel versions due to the addition of eBPF helper functions.

For more information on eBPF helper functions, check out (although slightly outdated) Marsden’s Oracle blog post.
