Enum EventAttribute 

pub enum EventAttribute {
    Stream(StreamName),
    Subject(Option<EventSubject>),
    EventType(EventType),
}

An event attribute for exact matching.

Variants

Stream(StreamName)

Match events in a specific stream.

Subject(Option<EventSubject>)

Match events with a specific subject (or no subject if None).

EventType(EventType)

Match events of a specific type.

Trait Implementations

impl Clone for EventAttribute

fn clone(&self) -> EventAttribute

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventAttribute

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

Formats the value using the given formatter.

impl From<EventAttribute> for EventAttribute

fn from(attr: EventAttribute) -> Self

Converts to this type from the input type.

impl Hash for EventAttribute

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 EventAttribute

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

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

fn partial_cmp(&self, other: &EventAttribute) -> 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 TryFrom<EventAttribute> for EventAttribute

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(proto: EventAttribute) -> Result<Self, Self::Error>

Performs the conversion.
