Enum Error 

#[non_exhaustive]
pub enum Error {
    SourceFailed {
        source_name: String,
        reason: String,
    },
    ReadFailed {
        path: PathBuf,
        reason: String,
    },
    CorruptData {
        path: PathBuf,
        reason: String,
    },
    EmptySource {
        pattern: String,
    },
    Shutdown,
    TransformFailed {
        index: u64,
        reason: String,
    },
    CollateFailed {
        reason: String,
    },
    Io(Arc<Error>),
    InvalidPattern(String),
    InvalidConfig {
        reason: String,
    },
}

All errors that can occur in the pipeline.

Note: This enum is #[non_exhaustive] because the pipeline architecture is designed to be extensible. We anticipate adding new variants in the future as we introduce new hardware integrations and data processing stages.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SourceFailed

A source failed to initialize or advance safely.

Fields

source_name: String

The source name.

reason: String

What went wrong.

ReadFailed

A source file could not be read.

Fields

path: PathBuf

The path that failed.

reason: String

Why it failed.

CorruptData

A source file was corrupt or unparseable.

Fields

path: PathBuf

The path containing corrupt data.

reason: String

What went wrong.

EmptySource

No files matched the source pattern.

Fields

pattern: String

The glob pattern that matched nothing.

Shutdown

The pipeline was shut down (Ctrl+C or explicit stop).

TransformFailed

A user-provided transform function failed.

Fields

index: u64

Which item in the stream caused the failure.

reason: String

What went wrong.

CollateFailed

Collation of a batch failed.

Fields

reason: String

What went wrong.

Io(Arc<Error>)

An I/O error occurred.

InvalidPattern(String)

A glob pattern was invalid.

InvalidConfig

Pipeline configuration was invalid.

Fields

reason: String

What was wrong.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<PatternError> for Error

fn from(e: PatternError) -> Self

Converts to this type from the input type.
