用法

基于示例/create.rs的创建者

//Create a MemFile at `pwd`\test.txt of size 4096
let mut mem_file: MemFile = match MemFile::create(PathBuf::from("test.txt"), 4096) {<...>};
//Set explicit scope for the lock (no need to call drop(shared_data))
{
   //Acquire write lock
   let mut shared_data = match mem_file.wlock_as_slice::<u8>() {<...>};
   let src = b"Some string you want to share\x00";
   //Write to the shared memory
   shared_data[0..src.len()].copy_from_slice(src);
}

基于示例/open.rs的从属者

// Open an existing MemFile from `pwd`\test.txt
let mut mem_file: MemFile = match MemFile::open(PathBuf::from("test.txt")) {<...>};
//Set explicit scope for the lock (no need to call drop(shared_data))
{
   //Acquire read lock
   let mut shared_data = match mem_file.rlock_as_slice::<u8>() {<...>};
   //Print the content of the shared memory as chars
   for byte in &shared_data[0..256] {
       if *byte == 0 { break; }
       print!("{}", *byte as char);
   }
}
