Struct StreamBufferConfig 

pub struct StreamBufferConfig {
    pub topic: String,
    pub correlation_id: Option<String>,
    pub capacity: Option<usize>,
}

Configuration for the correlated in-process stream response buffer.

Fields

topic: String

Shared buffer topic used by both the publisher and correlated consumers.

correlation_id: Option<String>

Consumer-only correlation id partition to read from.

Leave this unset for the publisher endpoint configured in HttpConfig::stream_response_to. Set it on consumers so a reader only receives messages belonging to one request or response stream.

capacity: Option<usize>

Capacity of each correlation partition. Defaults to 100.

Implementations

impl StreamBufferConfig

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

Creates a stream_buffer config for the given topic.

Add with_correlation_id when constructing a consumer for one stream. Leave the correlation id unset when constructing the publisher buffer used by HttpConfig::stream_response_to.

pub fn with_correlation_id(self, correlation_id: impl Into<String>) -> Self

Selects the response stream partition that a consumer should read.

pub fn with_capacity(self, capacity: usize) -> Self

Sets the per-correlation partition capacity.
