OS-specific extensions to fs::Metadata
.
fn as_raw_stat(&self) -> &stat
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.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; let stat = meta.as_raw_stat(); Ok(()) }
fn st_dev(&self) -> u64
1.8.0
Returns the device ID on which this file resides.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_dev()); Ok(()) }
fn st_ino(&self) -> u64
1.8.0
Returns the inode number.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_ino()); Ok(()) }
fn st_mode(&self) -> u32
1.8.0
Returns the file type and mode.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_mode()); Ok(()) }
fn st_nlink(&self) -> u64
1.8.0
Returns the number of hard links to file.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_nlink()); Ok(()) }
fn st_uid(&self) -> u32
1.8.0
Returns the user ID of the file owner.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_uid()); Ok(()) }
fn st_gid(&self) -> u32
1.8.0
Returns the group ID of the file owner.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_gid()); Ok(()) }
fn st_rdev(&self) -> u64
1.8.0
Returns the device ID that this file represents. Only relevant for special file.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_rdev()); Ok(()) }
fn st_size(&self) -> u64
1.8.0
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.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_size()); Ok(()) }
fn st_atime(&self) -> i64
1.8.0
Returns the last access time of the file, in seconds since Unix Epoch.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_atime()); Ok(()) }
fn st_atime_nsec(&self) -> i64
1.8.0
Returns the last access time of the file, in nanoseconds since st_atime
.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_atime_nsec()); Ok(()) }
fn st_mtime(&self) -> i64
1.8.0
Returns the last modification time of the file, in seconds since Unix Epoch.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_mtime()); Ok(()) }
fn st_mtime_nsec(&self) -> i64
1.8.0
Returns the last modification time of the file, in nanoseconds since st_mtime
.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_mtime_nsec()); Ok(()) }
fn st_ctime(&self) -> i64
1.8.0
Returns the last status change time of the file, in seconds since Unix Epoch.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_ctime()); Ok(()) }
fn st_ctime_nsec(&self) -> i64
1.8.0
Returns the last status change time of the file, in nanoseconds since st_ctime
.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_ctime_nsec()); Ok(()) }
fn st_blksize(&self) -> u64
1.8.0
Returns the "preferred" block size for efficient filesystem I/O.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_blksize()); Ok(()) }
fn st_blocks(&self) -> u64
1.8.0
Returns the number of blocks allocated to the file, 512-byte units.
use std::fs; use std::io; use std::os::linux::fs::MetadataExt; fn main() -> io::Result<()> { let meta = fs::metadata("some_file")?; println!("{}", meta.st_blocks()); Ok(()) }
