Struct TopicBuilder 

pub struct TopicBuilder<T>
where
    T: TopicBuilderState,
{ /* private fields */ }

Builder for SNS topics.

Supports both standard and FIFO topics with Lambda subscriptions. FIFO topics have additional configuration for deduplication and throughput.

Example

use rusty_cdk_core::stack::StackBuilder;
use rusty_cdk_core::sns::{TopicBuilder, SubscriptionType};

let mut stack_builder = StackBuilder::new();

// Create a simple topic without subscriptions
let simple_topic = TopicBuilder::new("simple-topic")
    .build(&mut stack_builder);
 
let function = unimplemented!("create a function");

// Create a topic with a Lambda subscription
let topic = TopicBuilder::new("my-topic")
    .add_subscription(SubscriptionType::Lambda(&function))
    .build(&mut stack_builder);

Implementations

impl TopicBuilder<StartState>

pub fn new(id: &str) -> TopicBuilder<StartState>

Creates a new SNS topic builder.

Arguments

• id - Unique identifier for the topic

pub fn add_subscription( self, subscription: SubscriptionType<'_>, ) -> TopicBuilder<StandardStateWithSubscriptions>

Adds a subscription to the topic.

For Lambda subscriptions, automatically creates the necessary permission.

pub fn build(self, stack_builder: &mut StackBuilder) -> TopicRef

impl TopicBuilder<StandardStateWithSubscriptions>

pub fn add_subscription( self, subscription: SubscriptionType<'_>, ) -> TopicBuilder<StandardStateWithSubscriptions>

pub fn build(self, stack_builder: &mut StackBuilder) -> TopicRef

impl<T> TopicBuilder<T>

where T: TopicBuilderState,

pub fn topic_name( self, topic_name: StringWithOnlyAlphaNumericsUnderscoresAndHyphens, ) -> TopicBuilder<T>

pub fn fifo(self) -> TopicBuilder<FifoState>

impl TopicBuilder<FifoState>

pub fn fifo_throughput_scope( self, scope: FifoThroughputScope, ) -> TopicBuilder<FifoState>

pub fn content_based_deduplication( self, content_based_deduplication: bool, ) -> TopicBuilder<FifoState>

pub fn add_subscription( self, subscription: SubscriptionType<'_>, ) -> TopicBuilder<FifoStateWithSubscriptions>

pub fn build(self, stack_builder: &mut StackBuilder) -> TopicRef

Builds the FIFO topic and adds it to the stack.

Automatically appends the required “.fifo” suffix to the topic name if not already present.

impl TopicBuilder<FifoStateWithSubscriptions>

pub fn fifo_throughput_scope( self, scope: FifoThroughputScope, ) -> TopicBuilder<FifoStateWithSubscriptions>

pub fn content_based_deduplication( self, content_based_deduplication: bool, ) -> TopicBuilder<FifoStateWithSubscriptions>

pub fn add_subscription( self, subscription: SubscriptionType<'_>, ) -> TopicBuilder<FifoStateWithSubscriptions>

pub fn build(self, stack_builder: &mut StackBuilder) -> TopicRef

Builds the FIFO topic with subscriptions and adds it to the stack.

Automatically appends the required “.fifo” suffix to the topic name if not already present. Creates Lambda permissions for all subscriptions.
