Struct BatchProcessResultBuilder 

pub struct BatchProcessResultBuilder { /* private fields */ }

Builder carrying validated parts for a crate::BatchProcessResult.

The builder checks that completed, processed, and chunk counters describe a consistent processing result before creating the result.

use std::time::Duration;

use qubit_batch::BatchProcessResultBuilder;

let result = BatchProcessResultBuilder::builder(3)
    .completed_count(3)
    .processed_count(3)
    .chunk_count(1)
    .elapsed(Duration::ZERO)
    .build()
    .expect("process result counters should be consistent");

assert!(result.is_success());
assert_eq!(result.chunk_count(), 1);

Implementations

impl BatchProcessResultBuilder

pub const fn builder(item_count: usize) -> Self

Starts building a batch process result.

Parameters

• item_count - Declared item count for the batch.

Returns

A builder initialized with zero counters and zero elapsed time.

pub const fn completed_count(self, completed_count: usize) -> Self

Sets the number of input items whose processing reached a terminal outcome.

Parameters

• completed_count - Number of completed input items.

Returns

The updated builder.

pub const fn processed_count(self, processed_count: usize) -> Self

Sets the number of items reported as successfully processed.

Parameters

• processed_count - Number of successfully processed items.

Returns

The updated builder.

pub const fn chunk_count(self, chunk_count: usize) -> Self

Sets the number of chunks submitted by the processor.

Parameters

• chunk_count - Number of submitted chunks.

Returns

The updated builder.

pub const fn elapsed(self, elapsed: Duration) -> Self

Sets the total monotonic elapsed duration.

Parameters

• elapsed - Total monotonic elapsed duration.

Returns

The updated builder.

pub fn validate(self) -> Result<Self, BatchProcessResultBuildError>

Validates this builder.

Returns

Ok(builder) when all counters are consistent.

Errors

Returns BatchProcessResultBuildError when the counters are inconsistent.

pub fn build(self) -> Result<BatchProcessResult, BatchProcessResultBuildError>

Validates this builder and creates a batch process result.

Returns

Ok(result) when all counters are consistent.

Errors

Returns BatchProcessResultBuildError when the counters are inconsistent.

Trait Implementations

impl Clone for BatchProcessResultBuilder

fn clone(&self) -> BatchProcessResultBuilder

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BatchProcessResultBuilder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for BatchProcessResultBuilder

fn eq(&self, other: &BatchProcessResultBuilder) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
