Struct solana_rbpf::syscalls::BpfTimeGetNs

pub struct BpfTimeGetNs {}

Get monotonic time (since boot time) in nanoseconds. All arguments are unused.

Examples

use solana_rbpf::syscalls::{BpfTimeGetNs, Result};
use solana_rbpf::memory_region::{MemoryRegion, MemoryMapping};
use solana_rbpf::vm::{Config, SyscallObject};
use solana_rbpf::user_error::UserError;

let mut result: Result = Ok(0);
let config = Config::default();
let memory_mapping = MemoryMapping::new::<UserError>(vec![MemoryRegion::default()], &config).unwrap();
BpfTimeGetNs::call(&mut BpfTimeGetNs {}, 0, 0, 0, 0, 0, &memory_mapping, &mut result);
let t = result.unwrap();
let d =  t / 10u64.pow(9)  / 60   / 60  / 24;
let h = (t / 10u64.pow(9)  / 60   / 60) % 24;
let m = (t / 10u64.pow(9)  / 60 ) % 60;
let s = (t / 10u64.pow(9)) % 60;
let ns = t % 10u64.pow(9);
println!("Uptime: {:#x} == {} days {}:{}:{}, {} ns", t, d, h, m, s, ns);
