Function read_to_string
in std::fs
https://doc.rust-lang.org/stable/std/fs/fn.read_to_string.html
Summary
The current documentation for std::fs::read_to_string
states that it is a convenience function for File::open
and std::io::Read::read_to_string
, providing fewer imports and no intermediate variables. However, after the recent pull request #110655, it seems that std::fs::read_to_string
has received performance improvements specifically for Windows, addressing issues that File::open
and std::io::Read::read_to_string
still face on this platform.
This implies that using std::fs::read_to_string
is not just a matter of convenience, but may also result in better performance on Windows compared to manually combining File::open
and std::io::Read::read_to_string
.
I believe this performance improvement should be mentioned in the documentation, especially for developers targeting Windows, as the current documentation only emphasizes the convenience aspect without mentioning the performance benefits.
Suggested change:
Add a note to the documentation of std::fs::read_to_string
, clarifying that due to recent improvements in pull request #110655, it offers better performance on Windows than manually using File::open
and std::io::Read::read_to_string
.
Thank you for your consideration!
