Enum cassandra_protocol::frame::events::SimpleServerEvent

#[non_exhaustive]
pub enum SimpleServerEvent {
    TopologyChange,
    StatusChange,
    SchemaChange,
}

Simplified ServerEvent that does not contain details about a concrete change. It may be useful for subscription when you need only string representation of an event.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Trait Implementations

impl Clone for SimpleServerEvent

fn clone(&self) -> SimpleServerEvent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SimpleServerEvent

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

Formats the value using the given formatter.

impl<'a> From<&'a ServerEvent> for SimpleServerEvent

fn from(event: &'a ServerEvent) -> SimpleServerEvent

Converts to this type from the input type.

impl From<ServerEvent> for SimpleServerEvent

fn from(event: ServerEvent) -> SimpleServerEvent

Converts to this type from the input type.

impl Hash for SimpleServerEvent

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 SimpleServerEvent

fn cmp(&self, other: &SimpleServerEvent) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<ServerEvent> for SimpleServerEvent

fn eq(&self, full_event: &ServerEvent) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<SimpleServerEvent> for ServerEvent

fn eq(&self, event: &SimpleServerEvent) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<SimpleServerEvent> for SimpleServerEvent

fn eq(&self, other: &SimpleServerEvent) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<SimpleServerEvent> for SimpleServerEvent

fn partial_cmp(&self, other: &SimpleServerEvent) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<&str> for SimpleServerEvent

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.
