Feature gate: #![feature(metadata_statx)]

This is a tracking issue for adding a constructor that constructs a std::fs::Metadata struct from a *const c_void pointer populated by the statx syscall.

Public API

// use std::os::linux::fs::MetadataExt;

pub const STATX_MASK: c_int;

impl MetadataExt for Metadata {
    unsafe fn from_statx(statxbuf: *const c_void) -> Metadata { ... }
}

Note: definition of this function is subject to change.

Unresolved Questions

• Ensure we're happy with the guarantees this asks from Linux, see Implement Metadata:from_statx for Linux MetadataExt trait #156269 (comment) and Implement Metadata:from_statx for Linux MetadataExt trait #156269 (comment). We may want to get an explicit guarantee from at least the mailing list (unclear as of writing if that has been asked for yet).
