OS-specific extension methods for `fs::Metadata`

## Required Methods

### `fn as_raw_stat(&self) -> &stat`

Deprecated since 1.8.0

: deprecated in favor of the accessor methods of this trait

This is supported on Linux only.

Gain a reference to the underlying `stat` structure which contains the raw information returned by the OS.

The contents of the returned `stat` are not consistent across Unix platforms. The `os::unix::fs::MetadataExt` trait contains the cross-Unix abstractions contained within the raw stat.

### `fn st_dev(&self) -> u64`
1.8.0

This is supported on Linux only.

Returns the device ID on which this file resides.

### `fn st_ino(&self) -> u64`
1.8.0

This is supported on Linux only.

Returns the inode number.

### `fn st_mode(&self) -> u32`
1.8.0

This is supported on Linux only.

Returns the file type and mode.

### `fn st_nlink(&self) -> u64`
1.8.0

This is supported on Linux only.

Returns the number of hard links to file.

### `fn st_uid(&self) -> u32`
1.8.0

This is supported on Linux only.

Returns the user ID of the file owner.

### `fn st_gid(&self) -> u32`
1.8.0

This is supported on Linux only.

Returns the group ID of the file owner.

### `fn st_rdev(&self) -> u64`
1.8.0

This is supported on Linux only.

Returns the device ID that this file represents. Only relevant for special file.

### `fn st_size(&self) -> u64`
1.8.0

This is supported on Linux only.

Returns the size of the file (if it is a regular file or a symbolic link) in bytes.

The size of a symbolic link is the length of the pathname it contains, without a terminating null byte.

### `fn st_atime(&self) -> i64`
1.8.0

This is supported on Linux only.

Returns the last access time.

### `fn st_atime_nsec(&self) -> i64`
1.8.0

This is supported on Linux only.

Returns the last access time, nano seconds part.

### `fn st_mtime(&self) -> i64`
1.8.0

This is supported on Linux only.

Returns the last modification time.

### `fn st_mtime_nsec(&self) -> i64`
1.8.0

This is supported on Linux only.

Returns the last modification time, nano seconds part.

### `fn st_ctime(&self) -> i64`
1.8.0

This is supported on Linux only.

Returns the last status change time.

### `fn st_ctime_nsec(&self) -> i64`
1.8.0

This is supported on Linux only.

Returns the last status change time, nano seconds part.

### `fn st_blksize(&self) -> u64`
1.8.0

This is supported on Linux only.

Returns the "preferred" blocksize for efficient filesystem I/O.

### `fn st_blocks(&self) -> u64`
1.8.0

This is supported on Linux only.

Returns the number of blocks allocated to the file, 512-byte units.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
