pub struct Metadata(_);
Metadata information about a file.
This structure is returned from the metadata or symlink_metadata function or method and represents known metadata about a file such as its permissions, size, modification times, etc.
impl Metadata
[src]
fn file_type(&self) -> FileTypeReturns the file type for this metadata.
use std::fs;
let metadata = fs::metadata("foo.txt")?;
println!("{:?}", metadata.file_type()); fn is_dir(&self) -> boolReturns whether this metadata is for a directory.
use std::fs;
let metadata = fs::metadata("foo.txt")?;
assert!(!metadata.is_dir()); fn is_file(&self) -> boolReturns whether this metadata is for a regular file.
use std::fs;
let metadata = fs::metadata("foo.txt")?;
assert!(metadata.is_file()); fn len(&self) -> u64Returns the size of the file, in bytes, this metadata is for.
use std::fs;
let metadata = fs::metadata("foo.txt")?;
assert_eq!(0, metadata.len()); fn permissions(&self) -> PermissionsReturns the permissions of the file this metadata is for.
use std::fs;
let metadata = fs::metadata("foo.txt")?;
assert!(!metadata.permissions().readonly()); fn modified(&self) -> Result<SystemTime>Returns the last modification time listed in this metadata.
The returned value corresponds to the mtime field of stat on Unix platforms and the ftLastWriteTime field on Windows platforms.
This field may not be available on all platforms, and will return an Err on platforms where it is not available.
use std::fs;
let metadata = fs::metadata("foo.txt")?;
if let Ok(time) = metadata.modified() {
println!("{:?}", time);
} else {
println!("Not supported on this platform");
} fn accessed(&self) -> Result<SystemTime>Returns the last access time of this metadata.
The returned value corresponds to the atime field of stat on Unix platforms and the ftLastAccessTime field on Windows platforms.
Note that not all platforms will keep this field update in a file's metadata, for example Windows has an option to disable updating this time when files are accessed and Linux similarly has noatime.
This field may not be available on all platforms, and will return an Err on platforms where it is not available.
use std::fs;
let metadata = fs::metadata("foo.txt")?;
if let Ok(time) = metadata.accessed() {
println!("{:?}", time);
} else {
println!("Not supported on this platform");
} fn created(&self) -> Result<SystemTime>Returns the creation time listed in the this metadata.
The returned value corresponds to the birthtime field of stat on Unix platforms and the ftCreationTime field on Windows platforms.
This field may not be available on all platforms, and will return an Err on platforms where it is not available.
use std::fs;
let metadata = fs::metadata("foo.txt")?;
if let Ok(time) = metadata.created() {
println!("{:?}", time);
} else {
println!("Not supported on this platform");
