Struct SubscriptionPattern 

pub struct SubscriptionPattern { /* private fields */ }

Represents a regular expression compatible with Google RE2/J, used to subscribe to topics.

This just keeps the String representation of the pattern; all validations to ensure it is RE2/J compatible are delegated to the broker (matching Java’s behavior).

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

Implementations

impl SubscriptionPattern

pub fn new(pattern: impl Into<String>) -> Self

Create a new SubscriptionPattern for the given regex pattern.

The pattern is stored as-is; no client-side validation is performed.

pub fn pattern(&self) -> &str

Returns the regular expression pattern compatible with RE2/J.

Trait Implementations

impl Clone for SubscriptionPattern

fn clone(&self) -> SubscriptionPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SubscriptionPattern

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

Formats the value using the given formatter.

impl Display for SubscriptionPattern

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

Formats the value using the given formatter.

impl Hash for SubscriptionPattern

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 SubscriptionPattern

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.
