Enum FailureCause 

pub enum FailureCause {
    NetworkUnavailable,
    ParseFailed,
    Timeout,
    EmptyContent,
    UnsupportedPageShape,
    ExtractionFailed,
    RendererFailed,
    ShelfUnavailable,
    LowConfidence,
    BlockedByPolicy,
    AdapterMismatch,
    Unknown,
}

Likely cause for a failed or low-confidence page.

Variants

NetworkUnavailable

Network fetch or DNS/transport failed.

ParseFailed

Local parsing failed or produced an unusable structure.

Timeout

A timeout stopped a fetch or rendering attempt.

EmptyContent

No useful page content was available.

UnsupportedPageShape

Index did not understand the static page shape.

ExtractionFailed

Extraction or serialization failed.

RendererFailed

Renderer layout or terminal output failed.

ShelfUnavailable

Local shelf storage or search failed.

LowConfidence

A document exists but Index has low confidence in its completeness.

BlockedByPolicy

A security or origin policy rejected the operation.

AdapterMismatch

A site adapter declined or failed and generic fallback was used.

Unknown

The cause was not specific enough to classify.

Implementations

impl FailureCause

pub const fn as_str(self) -> &'static str

Returns the stable cause name.

pub const fn explanation(self) -> &'static str

Returns concise user-facing cause text.

pub fn classify(source: DiagnosticSource, reason: &str) -> Self

Classifies a failure from its boundary and reason.

Trait Implementations

impl Clone for FailureCause

fn clone(&self) -> FailureCause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FailureCause

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

Formats the value using the given formatter.

impl Display for FailureCause

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

Formats the value using the given formatter.

impl PartialEq for FailureCause

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