RUST'S WORST FEATURE*

Summary from the TLDR Web Dev newsletter

This developer criticizes Rust's nightly `core::io::BorrowedBuf` feature, arguing it's a complex and flawed solution to the problem of unnecessary buffer initialization in I/O operations. The feature aims to allow reading into uninitialized memory, but its integration with existing code is poor and requires explicit support from various APIs, which could lead to potential misuse.
