Struct OpenedFileInfo 

pub struct OpenedFileInfo { /* private fields */ }

Stable file identity plus an optional metadata snapshot captured at open.

Examples

use qubit_fs::metadata::{FileKind, FileMetadata, FileSystemId, OpenedFileInfo};
use qubit_fs::path::Path;

let info = OpenedFileInfo::new(FileSystemId::new("doc")?, Path::parse("/report")?)
    .with_metadata(FileMetadata::new(FileKind::File));
assert_eq!("/report", info.path().as_str());

Implementations

impl OpenedFileInfo

pub fn new(filesystem_id: FileSystemId, path: Path) -> Self

Creates opened-file information without an extra metadata lookup.

Parameters

• filesystem_id: Stable identity of the filesystem that opened the handle.
• path: Logical resource path fixed at open time.

Returns

Opened-file information with no metadata snapshot.

pub fn with_metadata(self, metadata: FileMetadata) -> Self

Attaches metadata already obtained while opening the file.

Providers should not perform an extra remote stat only to populate this optional snapshot.

Parameters

• metadata: Metadata observed during open.

Returns

Updated opened-file information.

pub const fn filesystem_id(&self) -> &FileSystemId

Returns the stable opened location.

Returns

The location captured at open time.

pub const fn path(&self) -> &Path

Returns the logical path fixed when the provider opened the handle.

pub fn metadata(&self) -> Option<&FileMetadata>

Returns the optional metadata snapshot captured during open.

This is not live metadata. Call crate::FileSystem::stat when a current view is required.

Returns

The optional open-time snapshot.
