Struct DateFormat 

#[repr(C)]
pub struct DateFormat {
    pub era_number: i32,
    pub era_offset: u32,
    pub fraction: u64,
}

NTP Date Format - The prime epoch, or base date of era 0, is 0 h 1 January 1900 UTC, when all bits are zero. Dates are relative to the prime epoch; values greater than zero represent times after that date; values less than zero represent times before it.

Note that the era_offset field has the same interpretation as the seconds field of the TimestampFormat type.

Fields

era_number: i32

Era number (signed 32-bit integer).

era_offset: u32

Offset within the era in seconds (32-bit unsigned).

fraction: u64

Fractional seconds (64-bit unsigned).

Trait Implementations

impl Clone for DateFormat

fn clone(&self) -> DateFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ConstPackedSizeBytes for DateFormat

const PACKED_SIZE_BYTES: usize = 16

The constant size in bytes when this type is packed for network transmission.

impl Debug for DateFormat

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

Formats the value using the given formatter.

impl Default for DateFormat

fn default() -> DateFormat

Returns the “default value” for a type.

impl From<DateFormat> for Instant

fn from(d: DateFormat) -> Self

Converts a 128-bit NTP date format (with explicit era) to a Unix Instant.

This conversion is unambiguous because protocol::DateFormat includes the era number.

impl From<Instant> for DateFormat

fn from(t: Instant) -> Self

Converts a Unix Instant to a 128-bit NTP date format with explicit era.

This conversion preserves era information and is unambiguous.

impl FromBytes for DateFormat

fn from_bytes(buf: &[u8]) -> Result<(Self, usize), ParseError>

Parse from the given byte slice. Returns the parsed value and the number of bytes consumed from the front of buf.

impl Hash for DateFormat

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 DateFormat

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

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

fn partial_cmp(&self, other: &DateFormat) -> 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 ReadFromBytes for DateFormat

Available on crate feature std only.

fn read_from_bytes<R: ReadBytesExt>(reader: R) -> Result<Self>

Read the command from bytes.

impl ToBytes for DateFormat

fn to_bytes(&self, buf: &mut [u8]) -> Result<usize, ParseError>

Write this value into the given byte slice. Returns the number of bytes written. Fails with ParseError::BufferTooShort if buf is too short.

impl WriteToBytes for DateFormat

Available on crate feature std only.

fn write_to_bytes<W: WriteBytesExt>(&self, writer: W) -> Result<()>

Write the command to bytes.

impl Copy for DateFormat

impl Eq for DateFormat

impl StructuralPartialEq for DateFormat
