BatchResult

Struct BatchResult 

Source
pub struct BatchResult<T> {
    pub results: Vec<BatchItem<T>>,
    pub completion_reason: CompletionReason,
}
Expand description

Result of a parallel or map operation containing all branch outcomes.

§Examples

use durable_lambda_core::types::{BatchResult, BatchItem, BatchItemStatus, CompletionReason};

let result = BatchResult {
    results: vec![
        BatchItem { index: 0, status: BatchItemStatus::Succeeded, result: Some(42), error: None },
        BatchItem { index: 1, status: BatchItemStatus::Succeeded, result: Some(99), error: None },
    ],
    completion_reason: CompletionReason::AllCompleted,
};
assert_eq!(result.results.len(), 2);

Check per-item status after parallel/map — outer Ok does NOT mean all items succeeded:

use durable_lambda_core::types::{BatchResult, BatchItem, BatchItemStatus, CompletionReason};

let result = BatchResult {
    results: vec![
        BatchItem { index: 0, status: BatchItemStatus::Succeeded, result: Some(10), error: None },
        BatchItem { index: 1, status: BatchItemStatus::Failed, result: None, error: Some("timed out".into()) },
    ],
    completion_reason: CompletionReason::AllCompleted,
};

for item in &result.results {
    match item.status {
        BatchItemStatus::Succeeded => println!("item {} ok: {:?}", item.index, item.result),
        BatchItemStatus::Failed    => println!("item {} err: {:?}", item.index, item.error),
        BatchItemStatus::Started   => println!("item {} still running", item.index),
    }
}

// Collect only successful values:
let values: Vec<i32> = result.results.iter()
    .filter_map(|item| item.result)
    .collect();
assert_eq!(values, vec![10]);

Fields§

§results: Vec<BatchItem<T>>

Individual branch results, ordered by index.

§completion_reason: CompletionReason
