Enum EventStage 

pub enum EventStage<A, B, C> {
    Before(A),
    During(B),
    After(C),
}

An EventStage is a generic enumeration that represents the three stages of an event in a system, allowing for the association of a type T with each stage. The stages are:

• Before - the stage before the event occurs
• During - the stage while the event is occurring
• After - the stage after the event has occurred

Variants

Before(A)

During(B)

After(C)

Implementations

impl<A, B, C> EventStage<A, B, C>

pub const fn is_before(&self) -> bool

Returns true if the enum is EventStage::Before otherwise false

pub const fn is_during(&self) -> bool

Returns true if the enum is EventStage::During otherwise false

pub const fn is_after(&self) -> bool

Returns true if the enum is EventStage::After otherwise false

impl<A, B, C> EventStage<A, B, C>

pub const fn after(value: C) -> Self

a functional constructor for the After variant

pub const fn before(value: A) -> Self

a functional constructor for the Before variant

pub const fn during(value: B) -> Self

a functional constructor for the During variant

impl<A, B, C> IntoDiscriminant for EventStage<A, B, C>

type Discriminant = Stage

Enum listing the same variants as this enum but without any data fields

fn discriminant(&self) -> Self::Discriminant

impl<A: Ord, B: Ord, C: Ord> Ord for EventStage<A, B, C>

fn cmp(&self, other: &EventStage<A, B, C>) -> 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,
