Struct ClientQuotaEntity 

pub struct ClientQuotaEntity { /* private fields */ }

Describes a client quota entity, which is a mapping of entity types to their names.

Corresponds to org.apache.kafka.common.quota.ClientQuotaEntity.

Java models the mapping as a Map<String, String> whose values may be null: “If a name is null, then it is mapped to the built-in default entity name” (e.g. --entity-type users --entity-default). Rust cannot store a null String, so the faithful representation of Java’s nullable map value is Option<String>: None is the built-in default entity (wire-null entity name), and Some(name) is a concretely-named entity (Some(String::new()) is the entity literally named "", which is distinct from the default).

Implementations

impl ClientQuotaEntity

pub const USER: &str = "user"

The entity type value for a user.

pub const CLIENT_ID: &str = "client-id"

The entity type value for a client id.

pub const IP: &str = "ip"

The entity type value for an IP address.

pub fn is_valid_entity_type(entity_type: &str) -> bool

Returns whether the given entity type is one of the built-in types.

Mirrors ClientQuotaEntity.isValidEntityType.

pub fn new(entries: HashMap<String, Option<String>>) -> Self

Constructs a quota entity for the given types and names. If a name is None (Java null), then it is mapped to the built-in default entity name.

Mirrors ClientQuotaEntity(Map<String, String>).

pub fn entries(&self) -> &HashMap<String, Option<String>>

Returns the map of entity type to its name. A None value denotes the built-in default entity (Java’s null name).

Mirrors ClientQuotaEntity.entries().

Trait Implementations

impl Clone for ClientQuotaEntity

fn clone(&self) -> ClientQuotaEntity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClientQuotaEntity

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

Formats the value using the given formatter.

impl Display for ClientQuotaEntity

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

Formats the value using the given formatter.

impl Hash for ClientQuotaEntity

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 ClientQuotaEntity

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