Struct FileTime

source 
pub struct FileTime(/* private fields */);
Expand description

FileTime is a type that represents a Windows file time.

This is a 64-bit unsigned integer value that represents the number of 100-nanosecond intervals that have elapsed since “1601-01-01 00:00:00 UTC”, and is used as timestamps such as NTFS and 7z.

This represents the same value as the FILETIME structure of the Win32 API, which represents a 64-bit unsigned integer value. Note that the maximum value of the FILETIME structure that can be input to the FileTimeToSystemTime function of the Win32 API is limited to “+30828-09-14 02:48:05.477580700 UTC”, which is equivalent to i64::MAX.

Implementations§

source§

impl FileTime

source

pub const NT_TIME_EPOCH: Self = _

The NT time epoch.

This is defined as “1601-01-01 00:00:00 UTC”.

§Examples
assert_eq!(FileTime::NT_TIME_EPOCH, datetime!(1601-01-01 00:00 UTC));
source

pub const UNIX_EPOCH: Self = _

The Unix epoch.

This is defined as “1970-01-01 00:00:00 UTC”.

§Examples
assert_eq!(FileTime::UNIX_EPOCH, OffsetDateTime::UNIX_EPOCH);
source

pub const MAX: Self = _

The largest value that can be represented by the file time.

This is “+60056-05-28 05:36:10.955161500 UTC”.

§Examples
assert_eq!(
    FileTime::MAX,
    datetime!(+60056-05-28 05:36:10.955_161_500 UTC)
);

impl FileTime

source

pub fn to_dos_date_time( self, offset: Option<UtcOffset>, ) -> Result<(u16, u16, u8, Option<UtcOffset>), DosDateTimeRangeError>

Returns MS-DOS date and time which represents the same date and time as this FileTime. This date and time is used as the timestamp such as FAT, exFAT or ZIP file format.

This method returns a (date, time, resolution, offset) tuple if the result is Ok.

date and time represents the local date and time. This date and time has no notion of time zone. The resolution of MS-DOS date and time is 2 seconds, but additional finer resolution (10 ms units) can be provided. resolution represents this additional finer resolution.

When the offset parameter is Some, converts date and time from UTC to the local date and time in the provided time zone and returns it with the UTC offset. When the offset parameter is None or is not a multiple of 15 minute intervals, returns the UTC date and time as a date and time and None as the UTC offset.

§Errors

Returns Err if the resulting date and time is out of range for MS-DOS date and time.

§Panics

Panics if offset is out of range for the OffsetFromUtc field.

§Examples
// `1980-01-01 00:00:00 UTC`.
assert_eq!(
    FileTime::new(119_600_064_000_000_000)

assert_eq!(
    FileTime::new(159_992_927_990_000_000)
        .to_dos_date_time(None)
        .unwrap(),
    (0xff9f, 0xbf7d, 100, None)
);

// Before `1980-01-01 00:00:00 UTC`.
assert!(FileTime::new(119_600_063_990_000_000)
    .to_dos_date_time(None)
    .is_err());

assert!(FileTime::new(159_992_928_000_000_000)

assert_eq!(
    FileTime::new(126_828_411_000_000_000)

        .unwrap(),
    (0x2d7a, 0x9b20, u8::MIN, Some(offset!(-08:00)))
);

When the UTC offset is not a multiple of 15 minute intervals, returns the UTC date and time:

// `2002-11-27 03:25:00 UTC`.
assert_eq!(
    FileTime::new(126_828_411_000_000_000)

    (0x2d7a, 0x9940, u8::MIN, Some(offset!(-08:15)))
);
source

pub fn from_dos_date_time( date: u16, time: u16, resolution: Option<u8>, offset: Option<UtcOffset>, ) -> Result<Self, ComponentRange>

Creates a FileTime with the given MS-DOS date and time. This date and time is used as the timestamp such as FAT, exFAT or ZIP file format.

When resolution is Some, additional finer resolution (10 ms units) is added to time.

When offset is Some, converts date and time from the local date and time in the provided time zone to UTC. When offset is None or is not a multiple of 15 minute intervals, assumes the provided date and time is in UTC.

§Errors

Returns Err if date or time is an invalid date and time.

§Panics

Panics if any of the following are true:

§Examples
// `1980-01-01 00:00:00 UTC`.
assert_eq!(
    FileTime::from_dos_date_time(0x0021, u16::MIN, None, None).unwrap(),

// The DoubleSeconds field is 30.
assert!(FileTime::from_dos_date_time(0x0021, 0x001e, None, None).is_err());

When the UTC offset is not a multiple of 15 minute intervals, assumes the provided date and time is in UTC:

    FileTime::try_from(datetime!(1601-01-01 00:00 UTC)).unwrap(),
    FileTime::NT_TIME_EPOCH
);
assert_eq!(
    FileTime::try_from(OffsetDateTime::UNIX_EPOCH).unwrap(),
    FileTime::UNIX_EPOCH
);

// Before `1601-01-01 00:00:00 UTC`.
assert!(
    FileTime::try_from(datetime!(1601-01-01 00:00 UTC) - Duration::nanoseconds(100)).is_err()
);

With the large-dates feature enabled, returns Err if OffsetDateTime represents after “+60056-05-28 05:36:10.955161500 UTC”:

assert!(FileTime::try_from(
    datetime!(+60056-05-28 05:36:10.955_161_500 UTC) + Duration::nanoseconds(100)
)
.is_err());

source§

impl TryFrom<SystemTime> for FileTime

Available on crate feature std only.
source§

fn try_from(st: SystemTime) -> Result<Self, Self::Error>

Converts a SystemTime to a FileTime.

§Errors

Returns Err if time is out of range for the file time.

§Examples
assert_eq!(
    FileTime::try_from(SystemTime::UNIX_EPOCH - Duration::from_secs(11_644_473_600)).unwrap(),
    FileTime::NT_TIME_EPOCH
);
assert_eq!(
    FileTime::try_from(SystemTime::UNIX_EPOCH).unwrap(),
    FileTime::UNIX_EPOCH
);

// Before `1601-01-01 00:00:00 UTC`.
assert!(FileTime::try_from(
    SystemTime::UNIX_EPOCH - Duration::from_nanos(11_644_473_600_000_000_100)
)
.is_err());
// After `+60056-05-28 05:36:10.955161500 UTC`.
#[cfg(not(windows))]
assert!(FileTime::try_from(
    SystemTime::UNIX_EPOCH + Duration::new(1_833_029_933_770, 955_161_600)
)
.is_err());
source§

type Error = FileTimeRangeError

The type returned in the event of a conversion error.
source§

impl TryFrom<i64> for FileTime

source§

fn try_from(ft: i64) -> Result<Self, Self::Error>

Converts the file time to a FileTime.

The file time is sometimes represented as an i64 value, such as the winrt::clock struct in WinRT, or the DateTime.FromFileTime method and the DateTime.ToFileTime method in .NET.

§Errors

Returns Err if ft is negative.

§Examples
assert_eq!(FileTime::try_from(0_i64).unwrap(), FileTime::NT_TIME_EPOCH);
assert_eq!(
    FileTime::try_from(116_444_736_000_000_000_i64).unwrap(),
    FileTime::UNIX_EPOCH
);

assert!(FileTime::try_from(i64::MIN).is_err());
source§

type Error = FileTimeRangeError

The type returned in the event of a conversion error.
source§

impl UpperExp for FileTime

source§

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

Shows the underlying u64 value of this FileTime.

§Examples
assert_eq!(
    format!("{:024E}", FileTime::NT_TIME_EPOCH),
    "0000000000000000000000E0"
);
assert_eq!(format!("{:E}", FileTime::UNIX_EPOCH), "1.16444736E17");
assert_eq!(format!("{:E}", FileTime::MAX), "1.8446744073709551615E19");
source§

impl UpperHex for FileTime

source§

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

Shows the underlying u64 value of this FileTime.

§Examples
assert_eq!(format!("{:#X}", FileTime::NT_TIME_EPOCH), "0x0");
assert_eq!(format!("{:016X}", FileTime::UNIX_EPOCH), "019DB1DED53E8000");
assert_eq!(format!("{:X}", FileTime::MAX), "FFFFFFFFFFFFFFFF");
