Struct font_types::LongDateTime

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

A simple datetime type.

This represented as a number of seconds since 12:00 midnight, January 1, 1904, UTC.

Implementations

impl LongDateTime

pub const fn new(secs: i64) -> Self

Create with a number of seconds relative to 1904-01-01 00:00.

pub const fn as_secs(&self) -> i64

The number of seconds since 00:00 1904-01-01, UTC.

This can be a negative number, which presumably represents a date prior to the reference date.

pub const fn to_be_bytes(self) -> [u8; 8]

The representation of this datetime as a big-endian byte array.

Trait Implementations

impl Clone for LongDateTime

fn clone(&self) -> LongDateTime

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LongDateTime

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

Formats the value using the given formatter.

impl Default for LongDateTime

fn default() -> LongDateTime

Returns the “default value” for a type.

impl Hash for LongDateTime

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 LongDateTime

fn cmp(&self, other: &LongDateTime) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for LongDateTime

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

fn partial_cmp(&self, other: &LongDateTime) -> 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 Scalar for LongDateTime

type Raw = [u8; 8]

The raw byte representation of this type.

fn to_raw(self) -> [u8; 8]

Encode this type as raw big-endian bytes

fn from_raw(raw: [u8; 8]) -> Self

Create an instance of this type from raw big-endian bytes

fn read(slice: &[u8]) -> Option<Self>

Attempt to read a scalar from a slice.

impl Zeroable for LongDateTime

fn zeroed() -> Self

Calls zeroed.
