Enum PipelineError 

pub enum PipelineError {
    IoError(String),
    ItemError(String),
    DatabaseError(String),
    SerializationError(String),
    CsvError(String),
    Other(String),
}

Error type for item processing pipelines.

PipelineError represents errors that can occur during the processing of scraped items in pipelines, including I/O errors, database errors, serialization failures, and CSV operations.

Variants

• IoError: File system or I/O operation failures
• ItemError: General item processing failures
• DatabaseError: Database operation errors (e.g., SQLite)
• SerializationError: JSON/serialization failures
• CsvError: CSV reading/writing errors
• Other: Other unspecified pipeline errors

Example

use spider_util::error::PipelineError;

let err = PipelineError::IoError("File not found".to_string());
println!("Pipeline error: {}", err);

Variants

IoError(String)

I/O operation error.

ItemError(String)

Item processing error.

DatabaseError(String)

Database operation error.

SerializationError(String)

Serialization error.

CsvError(String)

CSV operation error.

Other(String)

Other unspecified pipeline error.

Trait Implementations

impl Clone for PipelineError

fn clone(&self) -> PipelineError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PipelineError

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

Formats the value using the given formatter.

impl Display for PipelineError

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

Formats the value using the given formatter.

impl Error for PipelineError

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
