Struct EpochTime 

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

Helper for validated epoch time construction.

Wraps a non-negative integer or finite float in the range 0 to 253402300799, as required by the CBOR::Core draft. Implements TryFrom for all integer and float primitives as well as SystemTime, so that Value::epoch_time can accept all of these through a single TryInto<EpochTime> bound.

Whole-second values are stored as integers; sub-second values (from floats or SystemTime with nanoseconds) are stored as floats. Converting to Value produces a tag 1 wrapper.

Trait Implementations

impl Clone for EpochTime

fn clone(&self) -> EpochTime

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpochTime

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

Formats the value using the given formatter.

impl From<EpochTime> for Value

fn from(value: EpochTime) -> Self

Converts to this type from the input type.

impl Ord for EpochTime

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

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

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