Struct Attrs 

pub struct Attrs { /* private fields */ }

Idiomatic metadata returned by the Rust-native path API.

Implementations

impl Attrs

pub fn present_mask(&self) -> AttrMask

Attribute fields actually returned by the backend, not merely requested.

Optional accessors remain None when a field was not requested or the backend could not provide it. Check this mask before projecting the metadata into an API that requires concrete values (such as stat).

pub fn absent_mask(&self, requested: AttrMask) -> AttrMask

Fields in requested that are absent from Self::present_mask. Unknown requested bits are preserved in the result.

pub fn contains(&self, requested: AttrMask) -> bool

Whether every field in requested is present, not merely any field. An empty mask is always contained.

pub fn mode(&self) -> Option<u32>

Full POSIX mode, including the file type bits, when returned.

pub fn blocks(&self) -> Option<u64>

Number of allocated 512-byte blocks, when returned.

pub fn device_id(&self) -> Option<u64>

Device identifier for a special file, when returned.

pub fn has_named_attributes(&self) -> Option<bool>

Whether named attributes exist, when the backend supplied this field.

pub fn file_type(&self) -> VfType

pub fn is_file(&self) -> bool

pub fn is_dir(&self) -> bool

pub fn is_symlink(&self) -> bool

pub fn len(&self) -> Option<u64>

Logical size, when SIZE was returned. Missing is distinct from zero.

pub fn is_empty(&self) -> Option<bool>

pub fn permissions(&self) -> Option<Permissions>

Permission bits, when MODE was returned. Missing is distinct from mode zero.

pub fn modified(&self) -> Option<SystemTime>

pub fn accessed(&self) -> Option<SystemTime>

pub fn changed(&self) -> Option<SystemTime>

POSIX status-change time; this is not a creation timestamp.

pub fn nlink(&self) -> Option<u32>

pub fn file_id(&self) -> Option<u64>

Backend file number, when returned; combine with Self::fs_id rather than comparing this number across filesystems.

pub fn fs_id(&self) -> Option<u128>

Backend filesystem ID, when returned. Pair it with file_id; it is not globally unique across servers or unrelated backend clients. NFS packs the FSID major part in the high 64 bits and minor part in the low.

pub fn fs_obj_id(&self) -> Option<FsObjId>

The underlying filesystem object ID when both components were returned.

pub fn change_id(&self) -> Option<u64>

pub fn uid(&self) -> Option<u32>

pub fn gid(&self) -> Option<u32>
