After importing the I/O ops trait via:
use crate::tools::io::ops::*;
Instead of:
let mut buffer = vec![0u8; 65536];
file.read_exact(&mut buffer)?;
use:
let buffer = file.read_exact_allocated(65536)?;
After importing the vector helpers via:
use crate::tools::vec::{self, ops::*};
For a buffer which *could* be uninitialized but you prefer
zero-initialization anyway for security reasons, instead of:
let mut buffer = vec![0u8; len];
use:
let mut buffer = vec::undefined(len);
which zero-initializes, but, if the `valgrind` feature flag
is enabled, marks the vector as having undefined contents,
so reading from it will cause valgrind errors.
