Struct solana_rbpf::syscalls::BpfGatherBytes

pub struct BpfGatherBytes {}

The idea is to assemble five bytes into a single u64. For compatibility with the syscalls API, each argument must be a u64.

Examples

use solana_rbpf::syscalls::{BpfGatherBytes, Result};
use solana_rbpf::memory_region::{MemoryRegion, MemoryMapping};
use solana_rbpf::vm::{Config, SyscallObject};

let mut result: Result = Ok(0);
let memory_mapping = [MemoryRegion::default()];
BpfGatherBytes::call(&mut BpfGatherBytes {}, 0x11, 0x22, 0x33, 0x44, 0x55, &MemoryMapping::new(memory_mapping.to_vec(), &Config::default()), &mut result);
assert_eq!(result.unwrap(), 0x1122334455);
