Enum IntervalType 

pub enum IntervalType {
    Opened,
    OpenedUndef,
    Closed,
    ClosedUndef,
}

Enumeration of range interval types.

Variants

Opened

Open-end interval with defined value, like (1.., ..10), ]1.. or ..10[.

OpenedUndef

Open-end interval without value, like (.., ..), ].. or ..[.

Closed

Closed-end interval with defined value, like [1.. or ..10].

ClosedUndef

Closed-end interval without value, like [.. or ..].

Implementations

impl IntervalType

pub fn opened(&self) -> bool

Return true when the interval is opened.

pub fn closed(&self) -> bool

Return true when the interval is closed.

pub fn undefined(&self) -> bool

Return true when the interval has no value defined.

Trait Implementations

impl Clone for IntervalType

fn clone(&self) -> IntervalType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntervalType

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

Formats the value using the given formatter.

impl Display for IntervalType

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

Formats the value using the given formatter.

impl PartialEq for IntervalType

fn eq(&self, other: &IntervalType) -> 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 Copy for IntervalType

impl Eq for IntervalType

impl StructuralPartialEq for IntervalType
