Enum CapabilityError 

pub enum CapabilityError {
    UnsupportedContractVersion(String),
    InvalidManifest(String),
    CapabilityUnavailable(String),
    Trap(String),
    InvalidOutput(String),
    ResourceExhausted(String),
    Cancelled,
    Timeout,
}

Everything ComponentValidator::validate or a real CapabilityEngine can fail with, named so the message alone tells the caller what to fix.

Split into two phases, matching the port’s own split: validation/load-time (UnsupportedContractVersion, InvalidManifest, CapabilityUnavailable — rejected before a route is ever registered) and invocation-time (Trap, InvalidOutput, ResourceExhausted, Cancelled, Timeout — surfaced from a live CapabilityEngine::invoke call). #1 scoped this enum down to only the first phase since no CapabilityEngine existed yet; #3 (ADR-001’s component engine wiring) adds the second phase back.

Variants

UnsupportedContractVersion(String)

The manifest’s contract_version is not one this host understands.

InvalidManifest(String)

The manifest or component bytes are structurally invalid.

CapabilityUnavailable(String)

A declared capability has no matching grant, or its scope is empty/wildcarded in a way its kind never permits, or (at engine time) a granted capability has no matching real dispatcher wired.

Trap(String)

The component trapped (panicked/aborted) during execution.

InvalidOutput(String)

The component produced output that does not match its declared export shape.

ResourceExhausted(String)

A configured memory, CPU, concurrency, or queue limit was exceeded.

Cancelled

The invocation was cancelled before it completed.

Timeout

The invocation exceeded its configured deadline.

Trait Implementations

impl Eq for CapabilityError

impl Error for CapabilityError

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 PartialEq for CapabilityError

fn eq(&self, other: &CapabilityError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
