Enum GroupProtocol 

#[non_exhaustive]
pub enum GroupProtocol {
    Classic,
    Consumer,
}

Enum representing the supported consumer group protocols.

• Classic - The Classic consumer group protocol (pre KIP-848)
• Consumer - The Consumer rebalance protocol (KIP-848)

Translation notes

KafkaConsumer::new supports only Consumer.

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.

Classic

Classic group protocol.

Consumer

Consumer group protocol (KIP-848).

Implementations

impl GroupProtocol

pub fn name(self) -> &'static str

String representation of the group protocol.

Returns

The upper-case name (e.g. "CLASSIC").

pub fn of(name: &str) -> Result<Self, Error>

Case-insensitive group protocol lookup by string name.

Arguments

• name - The name of the group protocol

Returns

The corresponding GroupProtocol

Errors

• Error::is_local_illegal_argument_error If the name does not match any protocol

Trait Implementations

impl Clone for GroupProtocol

fn clone(&self) -> GroupProtocol

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GroupProtocol

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

Formats the value using the given formatter.

impl Display for GroupProtocol

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

Formats the value using the given formatter.

impl FromStr for GroupProtocol

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for GroupProtocol

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

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 GroupProtocol

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

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

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