Fix `read_buf` uses in `std` Following lib-team decision here: https://github.com/rust-lang/rust/issues/78485#issuecomment-2122992314 Guard against the pathological behavior of both returning an error and performing a read.

2024-09-06properly handle EOF in BufReader::peekbinarycat-2/+2
previously this would cause an infinite loop due to it being unable to read `n` bytes.

2024-06-20Convert some module-level `//` and `///` comments to `//!`.Nicholas Nethercote-10/+11
This makes their intent and expected location clearer. We see some examples where these comments were not clearly separate from `use` declarations, which made it hard to understand what the comment is describing.

2022-07-24Remove some redundant checks from BufReaderBen Kimock-0/+75
The implementation of BufReader contains a lot of redundant checks. While any one of these checks is not particularly expensive to execute, especially when taken together they dramatically inhibit LLVM's ability to make subsequent optimizations.
