Enum GroupState 

#[non_exhaustive]
pub enum GroupState {
    Unknown,
    PreparingRebalance,
    CompletingRebalance,
    Stable,
    Dead,
    Empty,
    Assigning,
    Reconciling,
    NotReady,
}

The state of a group.

Corresponds to org.apache.kafka.common.GroupState.

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.

Unknown

An unrecognized group state (e.g. a state newer than this client).

PreparingRebalance

The group is preparing to rebalance.

CompletingRebalance

The group is completing a rebalance.

Stable

The group is stable.

Dead

The group is dead.

Empty

The group is empty.

Assigning

The group is assigning (consumer/streams groups only).

Reconciling

The group is reconciling (consumer/streams groups only).

NotReady

The group is not ready (streams groups only).

Implementations

impl GroupState

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

The display name of this group state (as used on the wire and in toString).

Mirrors the private name field in Java.

pub fn parse(name: &str) -> Self

Case-insensitive group state lookup by string name.

Returns GroupState::Unknown if the name is unrecognized, mirroring Java’s parse.

pub fn group_states_for_type(group_type: GroupType) -> HashSet<GroupState>

Returns the set of group states applicable to the given group type.

Mirrors GroupState.groupStatesForType.

Panics

Panics if type is GroupType::Unknown, mirroring Java’s IllegalArgumentException("Group type not known").

Trait Implementations

impl Clone for GroupState

fn clone(&self) -> GroupState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GroupState

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

Formats the value using the given formatter.

impl Display for GroupState

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

Formats the value using the given formatter.

impl Hash for GroupState

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 GroupState

fn eq(&self, other: &GroupState) -> 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.
