Enum TypedChannelError 

pub enum TypedChannelError {
    ChannelNotFound {
        name: String,
        registered: Vec<String>,
    },
    SchemaMismatch(String),
    CapabilityGate(String),
    LifetimeViolation {
        name: String,
        count: u32,
    },
    Transport(String),
}

Runtime errors raised by the typed-channel layer.

Each variant mirrors a compile-time diagnostic so a program that would have been rejected by the Fase 13.b type checker is also rejected here as defence-in-depth (relevant for cross-process publish/discover where the receiver cannot rerun static analysis).

Variants

ChannelNotFound

Channel name not in the registry.

Fields

name: String

registered: Vec<String>

SchemaMismatch(String)

Payload type does not match the channel schema.

The compile-time check (Fase 13.b _check_emit) catches this for statically-known programs; this runtime check is defence-in-depth.

CapabilityGate(String)

publish lacks a shield (D8) or discover targets an unpublishable channel / forged capability.

LifetimeViolation

An affine/linear handle was used after consumption.

Affine: at most one consumption (use OK; drop OK; reuse rejected). Linear: exactly one consumption (use required; reuse rejected). Persistent (!Channel): unrestricted reuse (no enforcement).

Fields

name: String

count: u32

Transport(String)

Underlying transport failure (closed channel, dropped sender).

Trait Implementations

impl Clone for TypedChannelError

fn clone(&self) -> TypedChannelError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypedChannelError

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

Formats the value using the given formatter.

impl Display for TypedChannelError

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

Formats the value using the given formatter.

impl Eq for TypedChannelError

impl Error for TypedChannelError

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<TypedChannelError> for DispatchError

fn from(e: TypedChannelError) -> Self

Converts to this type from the input type.

impl PartialEq for TypedChannelError

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