Struct FileIdentity 

pub struct FileIdentity {
    pub device: u64,
    pub inode: u64,
}

Native device/inode identity; callers own file-kind admission and persistence.

An identity does not freeze contents or prevent inode reuse after all held descriptors close. It establishes neither confinement nor namespace custody.

Fields

device: u64

Filesystem device number.

inode: u64

Inode number on that device.

Implementations

impl FileIdentity

pub fn from_file(file: &File) -> Result<Self>

Observe a caller-owned regular descriptor without reopening its path.

Errors

Returns metadata failures or rejects a non-regular descriptor.

pub fn from_metadata(metadata: &Metadata) -> Self

Observe native identity from metadata of any file kind.

Callers choose following or no-follow metadata and admit the file kind.
