Enum DetectError 

#[non_exhaustive]
pub enum DetectError {
    #[non_exhaustive]
    UnsupportedTarget {
        target_name: String,
        lattice: &'static str,
        coding: &'static str,
    },
    IncompleteBoard {
        found: usize,
        expected: usize,
    },
}

Detection-time failures reported by Detector methods.

All built-in lattice × coding combinations detect end-to-end, so detection itself is infallible; the only failure a Detector reports is the opt-in IncompleteBoard gate. This #[non_exhaustive] enum reserves room for future failure modes.

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.

#[non_exhaustive]

UnsupportedTarget

The configured target layout is not supported by the detection pipeline in this release.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

target_name: String

Name of the configured target layout.

lattice: &'static str

Lattice kind of the unsupported combination ("hex" or "rect").

coding: &'static str

Coding kind of the unsupported combination ("coded16" or "plain").

IncompleteBoard

The board was not fully detected while DetectConfig::require_complete_board was set. Returned only under the strict gate; otherwise incompleteness is reported non-fatally via DetectionResult::board_complete.

Fields

found: usize

Number of target cells that were labeled.

expected: usize

Total number of cells the target defines.

Trait Implementations

impl Clone for DetectError

fn clone(&self) -> DetectError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DetectError

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

Formats the value using the given formatter.

impl Display for DetectError

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

Formats the value using the given formatter.

impl Error for DetectError

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.
