Struct CompositeKeyStrategy 

pub struct CompositeKeyStrategy { /* private fields */ }

Generates session keys by composing multiple metadata fields.

This strategy builds session keys from a list of metadata fields in order, joining them with a separator. This is useful for creating hierarchical or compound session keys.

Example

use queue_runtime::sessions::CompositeKeyStrategy;

// Create session keys like "tenant-123-resource-456"
let strategy = CompositeKeyStrategy::new(vec![
    "tenant_id".to_string(),
    "resource_id".to_string(),
], "-");

Implementations

impl CompositeKeyStrategy

pub fn new(fields: Vec<String>, separator: &str) -> Self

Create a new composite key strategy.

Arguments

• fields - Ordered list of metadata field names to compose
• separator - String to join field values with

Example

use queue_runtime::sessions::CompositeKeyStrategy;

let strategy = CompositeKeyStrategy::new(
    vec!["region".to_string(), "customer_id".to_string()],
    "-"
);

Trait Implementations

impl SessionKeyGenerator for CompositeKeyStrategy

fn generate_key(&self, extractor: &dyn SessionKeyExtractor) -> Option<SessionId>

Generate a session key for the given message.
