Enum FrontierInterest 

pub enum FrontierInterest {
    Never,
    IfCapability,
    Always,
}

The ways in which an operator can express interest in activation when an input frontier changes.

Variants

Never

Never interested in frontier changes, as for example the map() and filter() operators.

IfCapability

Interested when the operator holds capabilities.

Always

Always interested in frontier changes, as for example the probe() and capture() operators.

Trait Implementations

impl Clone for FrontierInterest

fn clone(&self) -> FrontierInterest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrontierInterest

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

Formats the value using the given formatter.

impl Ord for FrontierInterest

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

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

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