Struct Time

pub struct Time { /* private fields */ }

Represents a point in time for file system operations.

Time_type stores time as seconds since the Unix epoch (January 1, 1970). It’s used throughout the file system for tracking file creation, modification, and access times. The type is designed to be efficient for storage and comparison.

Examples

use file_system::Time_type;

// Create a time representing the Unix epoch
let epoch = Time_type::new(0);
assert_eq!(epoch.As_u64(), 0);

// Create a time for a specific moment
let time = Time_type::new(1642684800); // January 20, 2022

Storage

Times are stored as 64-bit unsigned integers representing seconds, providing a range from 1970 to approximately year 584 billion, which is sufficient for any practical file system use.

Implementations

impl Time

pub const fn new(seconds: u64) -> Self

Create a new time from seconds since Unix epoch.

Arguments

• Seconds - Number of seconds since January 1, 1970 00:00:00 UTC

Examples

use file_system::Time_type;

let time = Time_type::new(1640995200); // January 1, 2022

pub const fn as_u64(self) -> u64

Get the time as seconds since Unix epoch.

Returns

Number of seconds since January 1, 1970 00:00:00 UTC.

Examples

use file_system::Time_type;

let time = Time_type::new(1640995200);
assert_eq!(time.As_u64(), 1640995200);

Trait Implementations

impl Clone for Time

fn clone(&self) -> Time

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Time

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

Formats the value using the given formatter.

impl Display for Time

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

Formats the value using the given formatter.

impl From<Duration> for Time

Convert from a duration to a time.

This treats the duration as an absolute time since the Unix epoch.

fn from(duration: Duration) -> Self

Converts to this type from the input type.

impl From<Time> for Duration

Convert from a time to a duration.

This converts the absolute time to a duration since the Unix epoch.

fn from(time: Time) -> Self

Converts to this type from the input type.

impl Hash for Time

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 Time

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

fn eq(&self, other: &Time) -> 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 Time

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