Struct DataKind 

pub struct DataKind(/* private fields */);

Type of filesystem object represented by an entry.

Each value determines how the entry’s data should be interpreted and how the entry should be extracted to the filesystem. Values without an associated constant are either reserved for future PNA specification (raw value < 128) or application-specific private values (raw value >= 128).

Implementations

impl DataKind

pub const FILE: Self

Regular file. Entry data contains the file contents.

pub const DIRECTORY: Self

Directory. Entry has no data content.

pub const SYMBOLIC_LINK: Self

Symbolic link. Entry data contains the UTF-8 encoded link target path.

pub const HARD_LINK: Self

Hard link. Entry data contains the UTF-8 encoded path of the target entry within the same archive.

pub const File: Self = Self::FILE

👎Deprecated since 0.36.0:

renamed to DataKind::FILE

Deprecated alias of DataKind::FILE.

pub const Directory: Self = Self::DIRECTORY

👎Deprecated since 0.36.0:

renamed to DataKind::DIRECTORY

Deprecated alias of DataKind::DIRECTORY.

pub const SymbolicLink: Self = Self::SYMBOLIC_LINK

👎Deprecated since 0.36.0:

renamed to DataKind::SYMBOLIC_LINK

Deprecated alias of DataKind::SYMBOLIC_LINK.

pub const HardLink: Self = Self::HARD_LINK

👎Deprecated since 0.36.0:

renamed to DataKind::HARD_LINK

Deprecated alias of DataKind::HARD_LINK.

pub const fn from_byte(value: u8) -> Self

Deserializes a data kind from its u8 representation.

Every byte value is a valid data kind, so this conversion never fails.

pub const fn to_byte(self) -> u8

Serializes this data kind to its u8 representation.

pub const fn new_private(value: u8) -> Option<Self>

Creates an application-specific private value.

Returns Some if value is in the private range (128..=255), otherwise None.

pub const fn try_from(value: u8) -> Result<Self, UnknownValueError>

👎Deprecated since 0.36.0:

use DataKind::from_byte

Converts a u8 into a DataKind. Never fails.

Shadows <DataKind as TryFrom<u8>>::try_from so existing DataKind::try_from(..) call sites receive a deprecation warning; both will be removed together in a future release.

Errors

Never returns Err; every byte value is a valid data kind.

pub const fn is_reserved(self) -> bool

Returns true if this value is reserved for future PNA specification (unassigned and raw value < 128).

pub const fn is_private(self) -> bool

Returns true if this is an application-specific private value (raw value >= 128).

Trait Implementations

impl Clone for DataKind

fn clone(&self) -> DataKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DataKind

impl Debug for DataKind

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

Formats the value using the given formatter.

impl Eq for DataKind

impl Hash for DataKind

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 DataKind

fn cmp(&self, other: &DataKind) -> 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 DataKind

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for DataKind

fn partial_cmp(&self, other: &DataKind) -> 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.

impl StructuralPartialEq for DataKind

impl TryFrom<u8> for DataKind

Infallible; kept for backward compatibility with the former enum-based API and scheduled for removal in a future release. Use DataKind::from_byte instead.

type Error = UnknownValueError

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.
