Enum GroupProtocol 

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

The group protocol that the consumer uses.

Corresponds to Java’s org.apache.kafka.clients.consumer.GroupProtocol.

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

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

Corresponds to Java GroupProtocol.name.

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

Case-insensitive lookup by string name.

Corresponds to Java GroupProtocol.of(String).

Errors

Returns Error::LocalIllegalArgument if name is not a recognized group protocol (matching Java’s IllegalArgumentException from Enum.valueOf).

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

Lower-case representation matching Java’s toString().toLowerCase(Locale.ROOT) pattern used in ConsumerConfig.DEFAULT_GROUP_PROTOCOL.

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 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.
