Enum WafClassifyError 

#[non_exhaustive]
pub enum WafClassifyError {
    BuildError(String),
    ClassifyError(String),
}

Errors returned by WafClassifier::classify.

BuildError is for classifier-internal construction problems (TOML parse failures, AC matcher build failures). ClassifyError is for per-call problems (e.g. response body decoding failures).

The engine treats both variants as None for dispatch purposes and logs them at WARN — a misconfigured classifier does NOT crash the dispatcher.

Examples

let build_err = WafClassifyError::BuildError("invalid toml".to_string());
let classify_err = WafClassifyError::ClassifyError("bad encoding".to_string());

match build_err {
    WafClassifyError::BuildError(msg) => println!("Build failed: {}", msg),
    WafClassifyError::ClassifyError(msg) => println!("Classify failed: {}", msg),
    // `#[non_exhaustive]`: callers outside the crate must include a wildcard
    // so future variants do not break their match.
    _ => println!("other classify error"),
}

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.

BuildError(String)

Classifier construction failed (e.g. TOML parse or AC build error).

ClassifyError(String)

Per-call classification failure (e.g. response body decoding error).

Trait Implementations

impl Clone for WafClassifyError

fn clone(&self) -> WafClassifyError

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
