[arennow]

Feature gate: #![feature(dir_entry_ext2)]

This is a tracking issue for a new method on std::fs::DirEntry on UNIX platforms via a new sealed variant of the std::os::unix::fs::DirEntryExt trait.

Public API

#[unstable(feature = "dir_entry_ext2")]
pub trait DirEntryExt2: Sealed {
    fn file_name_ref(&self) -> &OsStr;
}

Steps / History

• Implementation: Add std::os::unix::fs::DirEntryExt2::file_name_ref(&self) -> &OsStr #83581
• Final commenting period (FCP)
• Stabilization PR

Unresolved Questions

• What is an appropriate name for this new trait?

Hey, @arennow and @m-ou-se, is it possible to have an owned version of this function?

(self) -> OsString

Something like this in the trait

#[unstable(feature = "dir_entry_ext2")]
pub trait DirEntryExt2: Sealed {
    fn file_name_ref(&self) -> &OsStr;
    fn into_file_name(self) -> OsStr;
}

@marcospb19 An owned version is already available from DirEntry::file_name()

Hi @arennow and @m-ou-se

Is it planned to make this change stable in a coming release ?
The change seems to be a good optimization (typically for sorting DirEntry-s), without any risk of issue.
