Struct SingleFieldStrategy 

pub struct SingleFieldStrategy { /* private fields */ }

Generates session keys from a single metadata field.

This is the simplest strategy: extract one field and use it as the session key. Optionally adds a prefix for namespacing.

Example

use queue_runtime::sessions::SingleFieldStrategy;

// Create session keys from "user_id" like "user-12345"
let strategy = SingleFieldStrategy::new("user_id", Some("user"));

Implementations

impl SingleFieldStrategy

pub fn new(field_name: &str, prefix: Option<&str>) -> Self

Create a new single field strategy.

Arguments

• field_name - The metadata field to use for the session key
• prefix - Optional prefix to add before the field value

Example

use queue_runtime::sessions::SingleFieldStrategy;

let strategy = SingleFieldStrategy::new("order_id", Some("order"));
// Produces keys like "order-123"
