Enum SpiderError 

pub enum SpiderError {
    ReqwestError(ReqwestError),
    UrlParseError(ParseError),
    JsonError(String),
    IoError(String),
    ConfigurationError(String),
    GeneralError(String),
    ItemToStringError(String),
    ItemSerializationError(String),
    Unknown,
    InvalidHeaderValue(String),
    HeaderValueError(String),
    HtmlParseError(String),
    Utf8Error(Utf8Error),
    PipelineError(PipelineError),
    BlockedByRobotsTxt,
}

The main error type for the spider framework.

SpiderError encompasses all possible errors that can occur during web scraping operations, from network failures to data processing issues.

Variants

• Network Errors: ReqwestError for HTTP client errors
• URL Errors: UrlParseError for invalid URLs
• Serialization Errors: JsonError for JSON parsing/serialization
• I/O Errors: IoError for file system operations
• Configuration Errors: ConfigurationError for invalid settings
• Pipeline Errors: PipelineError for item processing failures
• HTML/UTF-8 Errors: Parse errors for HTML and UTF-8 content
• Robots.txt: BlockedByRobotsTxt for blocked requests

Example

use spider_util::error::SpiderError;
use url::Url;

// Handle different error types
match Url::parse("not-a-url") {
    Ok(url) => println!("Valid URL: {}", url),
    Err(SpiderError::UrlParseError(e)) => println!("Invalid URL: {}", e),
    Err(e) => println!("Other error: {}", e),
}

Trait Implementations

impl Clone for SpiderError

fn clone(&self) -> SpiderError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpiderError

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

Formats the value using the given formatter.

impl Display for SpiderError

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

Formats the value using the given formatter.

impl Error for SpiderError

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.
