Granularity of a temporal expression.

Temporal expressions exist at different levels of specificity, analogous to how entities exist at different levels of abstraction in a hierarchical clustering layer (currently archived out of the main workspace).

Implementations

impl TemporalGranularity

pub fn level(&self) -> u8

Get the numeric level (0 = most specific, higher = more abstract).

pub fn is_groundable(&self) -> bool

Can this granularity be converted to a concrete DateTime?

Trait Implementations

impl Clone for TemporalGranularity

fn clone(&self) -> TemporalGranularity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TemporalGranularity

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

Formats the value using the given formatter.

impl Default for TemporalGranularity

fn default() -> TemporalGranularity

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TemporalGranularity

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TemporalGranularity

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 TemporalGranularity

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

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

fn partial_cmp(&self, other: &TemporalGranularity) -> 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 Serialize for TemporalGranularity

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TemporalGranularity

impl Eq for TemporalGranularity

impl StructuralPartialEq for TemporalGranularity
