Enum GroupMembershipOperation 

#[non_exhaustive]
pub enum GroupMembershipOperation {
    LeaveGroup,
    RemainInGroup,
    Default,
}

Enum to specify the group membership operation upon leaving a group.

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.

LeaveGroup

The consumer will leave the group. This is the default for dynamic members, and can be used by static members when they want to permanently leave the group and trigger a rebalance.

RemainInGroup

The consumer will remain in the group. This is the default for static members, allowing them to rejoin quickly without triggering a rebalance. When used by dynamic members, no leave heartbeat will be sent and the member will be removed by the coordinator after the session timeout expires.

Default

Applies the default behavior:

• For static members: The consumer will remain in the group.
• For dynamic members: The consumer will leave the group.

Trait Implementations

impl Clone for GroupMembershipOperation

fn clone(&self) -> GroupMembershipOperation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GroupMembershipOperation

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

Formats the value using the given formatter.

impl Display for GroupMembershipOperation

Java’s inherited Enum.toString(): the constant’s name.

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

Formats the value using the given formatter.

impl Hash for GroupMembershipOperation

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 GroupMembershipOperation

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

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

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