Struct Metadata

pub struct Metadata { /* private fields */ }

Metadata information about a file.

Implementations

impl Metadata

pub fn file_type(&self) -> FileType

Get the file type.

pub fn is_dir(&self) -> bool

Return true if this metadata is for a directory.

pub fn is_symlink(&self) -> bool

Return true if this metadata is for a symlink.

pub fn len(&self) -> u64

Get the size in bytes of the file.

pub fn mode(&self) -> u16

Get the file’s UNIX permission bits.

Diagram of the returned value’s bits:

      top four bits are always zero
      │   
      │   set uid, set gid, sticky bit
      │   │  
      │   │  owner read/write/execute
      │   │  │  
      │   │  │  group read/write/execute
      │   │  │  │  
      │   │  │  │  other read/write/execute
      │   │  │  │  │
(msb) 0000xxxuuugggooo (lsb)

See st_mode in inode(7) for more details.

pub fn uid(&self) -> u32

Owner user ID.

pub fn gid(&self) -> u32

Owner group ID.

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metadata

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

Formats the value using the given formatter.

impl Hash for Metadata

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Metadata

fn cmp(&self, other: &Metadata) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Metadata

fn eq(&self, other: &Metadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Metadata

fn partial_cmp(&self, other: &Metadata) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
