Struct ResponseDegeneracy 

pub struct ResponseDegeneracy {
    pub family_label: &'static str,
    pub kind: ResponseDegeneracyKind,
}

Degenerate-response detail produced by ResponseFamily::validate_response_degeneracy.

Mirrors ResponseSupportViolation: it owns its own Display and message_for(column_name) so call sites in the workflow, the CLI, and any future binding produce identical user-facing prose without coupling each one to the family-internal classifier.

Fields

family_label: &'static str

kind: ResponseDegeneracyKind

Implementations

impl ResponseDegeneracy

pub fn message_for(&self, response_name: &str) -> String

Format the degeneracy against a specific response column name. The column name is supplied by the caller because ResponseFamily does not know which column the user pointed at.

Trait Implementations

impl Clone for ResponseDegeneracy

fn clone(&self) -> ResponseDegeneracy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResponseDegeneracy

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

Formats the value using the given formatter.

impl Display for ResponseDegeneracy

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

Formats the value using the given formatter.

impl Error for ResponseDegeneracy

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.
