    pub permissions: Permissions,

Expand description

Complete metadata for a filesystem entry.

Contains all common metadata fields for files, directories, and symlinks. Returned by FsRead::metadata and FsInode::metadata_by_inode.

§Fields

FieldTypeDescription
file_typeFileTypeFile, Directory, or Symlink
sizeu64Size in bytes (0 for directories)
permissionsPermissionsUnix permission bits
createdSystemTimeCreation timestamp
modifiedSystemTimeLast modification timestamp
accessedSystemTimeLast access timestamp
inodeu64Unique identifier within filesystem
nlinku64Number of hard links

§Example

use anyfs_backend::{Metadata, FileType, Permissions};
use std::time::SystemTime;

let meta = Metadata {
    file_type: FileType::File,
    size: 1024,
    permissions: Permissions::from_mode(0o644),
    created: SystemTime::now(),
    modified: SystemTime::now(),
    accessed: SystemTime::now(),
    inode: 42,
    nlink: 1,
};

assert!(meta.is_file());
assert_eq!(meta.size, 1024);

§Default Value

The default creates a zero-sized file with standard permissions (0o644):

use anyfs_backend::{Metadata, FileType};

let meta = Metadata::default();
assert!(meta.is_file());
assert_eq!(meta.size, 0);

Fields§

§file_type: FileType

Type of the entry (file, directory, symlink).

§size: u64

Size in bytes.

§permissions: Permissions

Permissions.

§created: SystemTime

Creation time.

§modified: SystemTime

Last modification time.

§accessed: SystemTime

Last access time.

§inode: u64

Inode number (unique identifier within the filesystem).

§nlink: u64

Number of hard links.
