fn rdev(&self) -> u64
Returns the device ID of this file (if it is a special one).
use std::fs; use std::os::unix::fs::MetadataExt; let meta = fs::metadata("some_file")?; let device_id = meta.rdev();
fn size(&self) -> u64
Returns the total size of this file in bytes.
use std::fs; use std::os::unix::fs::MetadataExt; let meta = fs::metadata("some_file")?; let file_size = meta.size();
fn atime(&self) -> i64
Returns the time of the last access to the file.
use std::fs; use std::os::unix::fs::MetadataExt; let meta = fs::metadata("some_file")?; let last_access_time = meta.atime();
fn atime_nsec(&self) -> i64
Returns the time of the last access to the file in nanoseconds.

fn mtime(&self) -> i64
Returns the time of the last modification of the file.

fn mtime_nsec(&self) -> i64
Returns the time of the last modification of the file in nanoseconds.

fn ctime(&self) -> i64
Returns the time of the last status change of the file.

fn ctime_nsec(&self) -> i64
Returns the time of the last status change of the file in nanoseconds.

fn blksize(&self) -> u64
Returns the blocksize for filesystem I/O.
use std::fs; use std::os::unix::fs::MetadataExt; let meta = fs::metadata("some_file")?; let blocksize = meta.blksize();
fn blocks(&self) -> u64
Returns the number of blocks allocated to the file, in 512-byte units.
Please note that this may be smaller than st_size / 512
when the file has holes.
use std::fs; use std::os::unix::fs::MetadataExt; let meta = fs::metadata("some_file")?; let blocks = meta.blocks();
