Description
I tried this code: (while learning Rust using Rust by Example and experimenting with the format string syntax available via format!() and related macros)
fn main() {
use std::fmt::format;
// Note that 18446744073709551616 is usize::MAX + 1
// Positional Argument
let s = format(format_args!("{18446744073709551616}", "which arg?"));
assert!(s == "which arg?");
// Width
let s = format(format_args!("{:18446744073709551616}", "wide?"));
assert!(s == "wide?");
// Precision
let s = format(format_args!("{:.18446744073709551616}", "not truncated?"));
assert!(s == "");
}I expected to see this happen:
rustc to reject this code with a diagnostic message due to the out of range integers in the format string literals.
Instead, this happened:
rustc compiled the code without any warning or error. Running the generated executable does not produce any assertion errors. This seems to be caused by the integers in the format string literals silently overflowing and wrapping around to zero.
Note that when compiling the code with a selfbuilt debug build of rustc instead of the regular nightly build, rustc panics due to an 'attempt to add with overflow':
