Enum AllenRelation 

pub enum AllenRelation {
    Precedes,
    Meets,
    Overlaps,
    FinishedBy,
    Contains,
    Starts,
    Equals,
    StartedBy,

}

The 13 relations of Allen’s interval algebra.

Variants

Precedes

a ends strictly before b starts.

Meets

a ends exactly when b starts.

Overlaps

a starts before b and ends inside b.

FinishedBy

a starts before b and ends exactly when b ends.

Contains

a starts before b starts and ends after b ends.

Starts

a and b start at the same point; a ends before b.

Equals

a and b are identical.

StartedBy

a and b start at the same point; b ends before a.

During

a starts after b starts and ends before b ends (proper subset).

Finishes

a starts after b starts and ends exactly when b ends.

OverlappedBy

b starts before a and ends inside a.

MetBy

a starts exactly when b ends.

PrecededBy

a starts strictly after b ends.

Implementations

impl AllenRelation

pub fn classify(a: &TimeInterval, b: &TimeInterval) -> AllenRelation

Classify two intervals into exactly one Allen relation.

pub fn is_overlapping_kind(self) -> bool

Returns true when the two intervals share any common point under this relation (i.e. the relation is not a strict precede or strict follow).

Trait Implementations

impl Clone for AllenRelation

fn clone(&self) -> AllenRelation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AllenRelation

impl Debug for AllenRelation

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

Formats the value using the given formatter.

impl Eq for AllenRelation

impl Hash for AllenRelation

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 PartialEq for AllenRelation

fn eq(&self, other: &AllenRelation) -> 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.
