Enum ParallelBatchProcessorBuildError 

pub enum ParallelBatchProcessorBuildError {
    ZeroThreadCount,
}

Error returned when building a crate::ParallelBatchProcessor.

use qubit_batch::{
    ParallelBatchProcessor,
    ParallelBatchProcessorBuildError,
};

let error = match ParallelBatchProcessor::builder(|_item: &i32| {})
    .thread_count(0)
    .build()
{
    Ok(_) => panic!("zero worker count should be rejected"),
    Err(error) => error,
};

assert_eq!(error, ParallelBatchProcessorBuildError::ZeroThreadCount);

Variants

ZeroThreadCount

The configured worker-thread count is zero.

Trait Implementations

impl Clone for ParallelBatchProcessorBuildError

fn clone(&self) -> ParallelBatchProcessorBuildError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParallelBatchProcessorBuildError

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

Formats the value using the given formatter.

impl Display for ParallelBatchProcessorBuildError

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

Formats the value using the given formatter.

impl Error for ParallelBatchProcessorBuildError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ParallelBatchProcessorBuildError

fn eq(&self, other: &ParallelBatchProcessorBuildError) -> 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.
