Implementations

impl Inode

pub const SIZE: usize

Total on-disk size (base 160 + 96 bytes inline xattrs = 256).

pub fn read_from(buf: &[u8]) -> Self

pub fn write_to(&self, buf: &mut [u8])

pub fn root_inode() -> Self

Create the root directory inode (inode 2).

Sets S_IFDIR | 0o755, two links (. and ..), HUGE_FILE flag, and timestamps to the current wall-clock time.

pub fn is_dir(&self) -> bool

True if this inode represents a directory.

pub fn is_reg(&self) -> bool

True if this inode represents a regular file.

pub fn is_link(&self) -> bool

True if this inode represents a symbolic link.

pub fn file_size(&self) -> u64

Combine size_lo and size_hi into a 64-bit file size.

pub fn set_file_size(&mut self, size: u64)

Set the 64-bit file size, splitting into size_lo / size_hi.

pub fn uid_full(&self) -> u32

Full 32-bit UID (lo + hi).

pub fn gid_full(&self) -> u32

Full 32-bit GID (lo + hi).

pub fn set_uid(&mut self, uid: u32)

Set the full 32-bit UID, splitting into lo / hi.

pub fn set_gid(&mut self, gid: u32)

Set the full 32-bit GID, splitting into lo / hi.

Trait Implementations

impl Clone for Inode

fn clone(&self) -> Inode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Inode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Inode

fn default() -> Self

Returns the “default value” for a type.
