Struct QueueConfig 

pub struct QueueConfig {
    pub initial_delay: String,
    pub max_delay: String,
    pub backoff_multiplier: f64,
    pub max_attempts: u32,
    pub worker_threads: usize,
    pub batch_size: usize,
}

Outbound mail queue and retry configuration.

Fields

initial_delay: String

Required. Initial retry delay after the first failed delivery attempt, expressed as a human-readable duration (e.g. "60s", "1m").

max_delay: String

Required. Maximum retry delay after many consecutive failures, expressed as a human-readable duration (e.g. "3600s", "1h").

backoff_multiplier: f64

Required. Exponential back-off multiplier applied between retries. Must be positive. A value of 2.0 doubles the delay after each failure up to max_delay.

max_attempts: u32

Required. Maximum number of delivery attempts before the message is bounced back to the sender.

worker_threads: usize

Required. Number of threads in the queue worker pool. Must be > 0.

batch_size: usize

Required. Maximum number of messages to dequeue and attempt in a single batch. Larger values increase throughput at the cost of latency.
