Struct ConsumerError 

pub struct ConsumerError { /* private fields */ }

Opaque, typed consumer-side rejection.

The consumer surface owns a typed kernel error; the dispatcher must not flatten it into a bare string and lose the stable discriminant. This newtype is the dispatcher-facing projection of that typed error: it carries the consumer’s stable ConsumerError::error_code (the same &'static str convention used by meerkat_core::error) alongside a human-readable message. The dispatcher moves it across the seam verbatim, so DispatchRefusal::ConsumerRefused / SignalDispatchRefusal::ConsumerRefused expose the typed code rather than re-parsing a flattened reason string.

Implementations

impl ConsumerError

pub fn new(error_code: &'static str, message: impl Into<String>) -> Self

Build a consumer rejection from the consumer kernel’s stable error_code and a human-readable message.

pub fn error_code(&self) -> &'static str

Stable typed discriminant preserved across the dispatch seam.

pub fn message(&self) -> &str

Human-readable rejection detail.

Trait Implementations

impl Clone for ConsumerError

fn clone(&self) -> ConsumerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConsumerError

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

Formats the value using the given formatter.

impl Display for ConsumerError

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

Formats the value using the given formatter.

impl Eq for ConsumerError

impl Error for ConsumerError

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.

impl From<String> for ConsumerError

fn from(message: String) -> Self

Consumer-surface input projection/refusal detail that the kernel produced as a bare string is carried across the dispatch seam under a stable consumer_projection_failed discriminant (the string stays as human-readable detail, but the typed code is what the dispatcher and RMAT audits observe — never a re-parsed message).

impl PartialEq for ConsumerError

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