Expand description

Stores a file’s metadata in order to avoid code duplication in the different metadata related shims.

Some fields are host/platform-specific. `None` means that Miri does not have a real value for this field, for example because the metadata is synthetic or because the host platform does not expose it. `statx` must only advertise the corresponding `STATX_*` bit when the field is `Some`; legacy `stat` writes zero for `None` to preserve the old fallback behavior.

## Fields§

§`mode: u32`

This holds both the file type (dir, regular, symlink, …) and permissions.

§`size: u64`§`created: Option<(u64, u32)>`§`accessed: Option<(u64, u32)>`§`modified: Option<(u64, u32)>`§`dev: Option<u64>`§`ino: Option<u64>`§`nlink: Option<u64>`§`uid: Option<u32>`§`gid: Option<u32>`§`blksize: Option<u64>`§`blocks: Option<u64>`

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
