Scanner error types with detailed context

Variants

• NetworkError: HTTP client, connection, or response parsing failures
• UrlParseError: Invalid URL format or scheme
• PayloadGenerationError: Malformed payload generation parameters
• PhaseTimeout: Scanning phase exceeded timeout threshold
• TaskJoinFailed: A structurally owned scanner worker failed to join
• Cancelled: Host cancellation stopped bounded legacy transport
• BudgetExceeded: A bounded legacy resource threshold stopped work
• InvalidDiscoveryLimits: A discovery policy is incoherent or too large
• InvalidVerificationLimits: A verification policy is incoherent or too large
• DiscoveryStateLimitExceeded: A staged state transition exceeds retention bounds
• InvalidLegacyVerificationReport: A legacy phase attempted to bypass claim policy
• LegacyVerificationStateLimitExceeded: Verification outcome retention is exhausted
• InvalidTarget: Target URL doesn’t meet validation requirements
• IoError: File system or I/O operation failures

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.

NetworkError(String)

Network I/O failures with detailed error message

UrlParseError(String)

URL parsing failures with detailed error message

PayloadGenerationError(String)

Payload generation failures with detailed error message

PhaseTimeout

Phase execution timeout

TaskJoinFailed

A structurally owned worker task failed to join.

Deliberately carries no [tokio::task::JoinError] or panic payload so target-controlled panic details cannot cross the scanner boundary.

Cancelled

Host cancellation stopped bounded legacy transport.

BudgetExceeded(RuntimeLimitExceeded)

A shared bounded legacy resource limit denied or stopped work.

InvalidDiscoveryLimits

Discovery limits are zero, inconsistent, or exceed hard bounds.

InvalidVerificationLimits

Verification limits are zero, inconsistent, or exceed hard bounds.

DiscoveryStateLimitExceeded

A staged discovery update exceeded a deterministic state bound.

InvalidLegacyVerificationReport

A corrected legacy phase supplied a report outside the constrained active, knowledge-only, manual-review bridge.

LegacyVerificationStateLimitExceeded

Accepted legacy verification outcomes exceeded the report bound.

InvalidTarget

Target validation failure

IoError(Error)

File I/O operation failure

RunReport(RunReportError)

Typed run report construction failed closed.

Trait Implementations

impl Debug for ScannerError

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

Formats the value using the given formatter.

impl Display for ScannerError

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

Formats the value using the given formatter.

impl Error for ScannerError

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.
