Struct Metadata

pub struct Metadata { /* private fields */ }

Metadata information about an entry.

Examples

use libpna::Metadata;
use std::time::SystemTime;

let since_unix_epoch = SystemTime::now().duration_since(SystemTime::UNIX_EPOCH)?;
let metadata = Metadata::new()
    .with_accessed(Some(since_unix_epoch))
    .with_created(Some(since_unix_epoch))
    .with_modified(Some(since_unix_epoch));

Implementations

impl Metadata

pub const fn new() -> Self

Create a new Metadata.

pub const fn with_created(self, created: Option<Duration>) -> Self

Set created time that as duration since unix epoch time.

Examples

use libpna::Metadata;
use std::time::SystemTime;

let since_unix_epoch = SystemTime::now().duration_since(SystemTime::UNIX_EPOCH)?;
let metadata = Metadata::new().with_created(Some(since_unix_epoch));

pub const fn with_modified(self, modified: Option<Duration>) -> Self

Set modified time that as duration since unix epoch time.

Examples

use libpna::Metadata;
use std::time::SystemTime;

let since_unix_epoch = SystemTime::now().duration_since(SystemTime::UNIX_EPOCH)?;
let metadata = Metadata::new().with_modified(Some(since_unix_epoch));

pub const fn with_accessed(self, accessed: Option<Duration>) -> Self

Set accessed time that as duration since unix epoch time.

Examples

use libpna::Metadata;
use std::time::SystemTime;

let since_unix_epoch = SystemTime::now().duration_since(SystemTime::UNIX_EPOCH)?;
let metadata = Metadata::new().with_accessed(Some(since_unix_epoch));

pub fn with_permission(self, permission: Option<Permission>) -> Self

Set permission of entry.

pub const fn raw_file_size(&self) -> Option<u128>

Raw file size of entry data in bytes

pub const fn compressed_size(&self) -> usize

Compressed size of entry data in bytes

pub const fn created(&self) -> Option<Duration>

Created time since unix epoch time of entry

pub const fn modified(&self) -> Option<Duration>

Modified time since unix epoch time of entry

pub const fn accessed(&self) -> Option<Duration>

Accessed time since unix epoch time of entry

pub const fn permission(&self) -> Option<&Permission>

An owner, group, and permissions for an entry

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a copy 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 Default for Metadata

fn default() -> Self

Returns the “default value” for a type.

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.
