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) -> FileType
Returns the file type for this metadata.
use std::fs; let metadata = fs::metadata("foo.txt")?; println!("{:?}", metadata.file_type());
fn is_dir(&self) -> bool
Returns whether this metadata is for a directory.
use std::fs; let metadata = fs::metadata("foo.txt")?; assert!(!metadata.is_dir());
fn is_file(&self) -> bool
Returns whether this metadata is for a regular file.
use std::fs; let metadata = fs::metadata("foo.txt")?; assert!(metadata.is_file());
fn len(&self) -> u64
Returns 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) -> Permissions
Returns 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"); }
